Best Locksets for Exterior Doors in UK (2026 Update)

Most exterior door locksets look similar until you start comparing what’s inside them. One lock might resist snapping, drilling and picking. Another might meet none of the security standards most UK insurers expect. From the outside, you wouldn’t know the difference.

That’s why buying a front door lock isn’t about choosing the most expensive model or the biggest brand. It’s about matching the lock to your door, your home and the level of protection you need. In this guide, we’ll compare the best locksets for exterior doors, explain the standards behind today’s high security front door locks, and show you which products are worth considering in 2026.

Best Locksets For Exterior Doors

Walk into any hardware shop and you’ll see dozens of locks that look similar. They aren’t.

Some are designed for timber doors. Others only work with uPVC or composite doors. Some replace the entire lockset, while others upgrade only the cylinder. Understanding these differences will save you money and help you avoid buying a lock that doesn’t fit your door.

Deadbolts

Deadbolts remain one of the most common choices for exterior doors because they’re simple, durable and difficult to force open when installed correctly.

Unlike a spring latch, a deadbolt extends a solid metal bolt deep into the door frame. There’s no spring mechanism to slip with a credit card or similar tool. That extra resistance in these parts of door locks makes deadbolts a popular option for timber front doors throughout the UK.

You’ll generally find two versions.

Traditional keyed deadbolts

These use a key from the outside and either a thumb turn or another key on the inside. They’re reliable, require almost no maintenance and don’t depend on batteries or Wi-Fi.

They’re a good choice if you want:

• Proven mechanical security
• Low maintenance
• A long service life
• Simple operation

Keypad deadbolts

Keypad models replace physical keys with a PIN code. Most still include a traditional key as a backup, giving you another way to unlock the door if the batteries run out.

They’re useful if you:

• Regularly forget your keys
• Want different codes for family members
• Need temporary access for cleaners or contractors
• Don’t want a fully connected smart lock

Look for products with strong drill protection, reinforced strike plates and recognised security certifications.

Electronic Smart Locks

Smart locks replace or automate part of the locking process without changing the basic purpose of the lock. Instead of relying only on a physical key, you unlock your door using a phone, fingerprint, PIN code or voice assistant.

Some models replace the entire lockset. Others fit over your existing thumb turn, making installation much easier if you’re renting or don’t want to replace the original hardware.

The biggest advantage is convenience.

Instead of hiding spare keys under a flowerpot or rushing home to let someone in, you unlock the door from your phone or issue temporary digital keys that expire automatically.

Many smart locks also include features such as:

• Fingerprint recognition
• Apple HomeKit, Alexa and Google Home support
• Automatic locking after you leave
• Remote access
• Entry history
• Scheduled access for guests

Interesting to know: Security often worries first-time buyers. In reality, a quality smart lock is usually no easier to attack than a standard lock. Most successful break-ins still target the cylinder, door frame or glass rather than trying to hack the software.

For UK homes, we would still prioritise the physical security of the lock over the app features. Strong anti-snap protection matters far more than another automation setting.

Keyless Entry Systems

People often use “smart lock” and “keyless entry” interchangeably, but they aren’t always the same thing.

A keyless entry system simply lets you unlock the door without inserting a physical key.

That might include:

• PIN keypad
• Fingerprint reader
• NFC card
• Smartphone app
• Bluetooth credentials
• Facial recognition on premium systems

Some keyless locks don’t even connect to the internet. They store authorised users locally, which appeals to homeowners who want modern access control without relying on cloud services.

They’re especially useful if several people need regular access to the property.

Instead of cutting multiple keys, you simply assign each person their own code or fingerprint. If someone moves out or loses access rights, deleting their credentials takes seconds. There’s no need to replace the entire lock.

Also: For holiday lets and Airbnb properties, keyless entry also removes the hassle of key collection and returns.

Euro Cylinders

If your home has a uPVC or composite front door, the euro cylinder is often the weakest part of the locking system.

The multipoint mechanism inside the door might be strong, but an older cylinder without anti-snap protection gives burglars an obvious point of attack.

Replacing the cylinder is usually faster and cheaper than replacing the complete lockset.

Modern high-security cylinders typically include:

• Anti-snap sections
• Drill-resistant inserts
• Pick-resistant pins
• Anti-bump protection
• Reinforced cam designs

Look for cylinders with a TS007 3-Star rating or combine a 1-Star cylinder with approved security door furniture if you’re upgrading an existing installation.

Cylinder sizing also matters. A cylinder that sticks out beyond the handle gives intruders more material to grip and snap. Measure carefully before ordering a replacement.

Multi-point Locking Systems

Most modern composite and uPVC front doors use a multi-point locking system instead of a single deadbolt.

When you lift the handle or turn the key, the mechanism locks the door at several points along the frame rather than in one location.

Depending on the design, those locking points might include:

• Hooks
• Rollers
• Deadbolts
• Mushroom cams
• Shoot bolts

This spreads force across the height of the door and makes forced entry much more difficult than attacking a single locking point.

Remember, though, the multipoint strip isn’t usually what fails first.

In many cases, upgrading the euro cylinder provides a larger security improvement than replacing the complete multipoint mechanism.

That makes the cylinder one of the best-value security upgrades available for many UK homes.

Mortice Locks (Timber Doors)

If your home has a traditional timber front door, a mortice lock is usually the strongest mechanical option available. Unlike a rim lock or standard latch, a mortice lock sits inside a pocket cut into the door itself, making it much harder to remove or force from the outside.

You’ll mainly come across two types.

Sashlocks combine a deadbolt and a latch in one lock body. They’re operated by both a key and a handle, making them the most common choice for front doors.

Deadlocks only contain a deadbolt. They don’t have a sprung latch, so the door must be locked with a key every time you leave. Many homeowners install a deadlock alongside a night latch for extra security.

Keep in mind: If you’re replacing a front door lock on a timber property, check whether your insurer requires a BS3621-certified mortice lock. Many policies specify this standard for external timber doors.

Quick Comparison of Exterior Door Lock Types

Security Standards

Manufacturers often advertise hardened steel, military-grade construction or reinforced components, but those claims don’t tell you how a lock performs under recognised testing. Independent security standards do.

If you’re comparing the best front door locks, ignore the marketing first. Look for recognised certifications. They’re a much better indicator of how well a lock resists common attacks such as drilling, snapping, picking and forced entry.

Remember: For UK homeowners, insurance approval matters as much as physical strength. Some insurers specify minimum lock standards, especially for external timber doors.

ANSI/BHMA Ratings

You’ll see ANSI/BHMA grades on many American locks, including several smart locks sold in the UK.

ANSI stands for the American National Standards Institute, while BHMA is the Builders Hardware Manufacturers Association. Together they test residential and commercial door hardware for strength, durability and cycle life.

Although UK buyers usually pay more attention to TS007 or BS3621, ANSI grades still provide a useful way to compare imported deadbolts and smart locks.

Grade 1: Maximum Security

Grade 1 is the highest residential rating.

Locks at this level withstand the largest number of operating cycles and the greatest amount of force during testing. They’re designed for heavy use in commercial buildings, apartment entrances and high-traffic properties.

You’ll often find Grade 1 certification on premium smart deadbolts and commercial locksets.

Choose Grade 1 if:

• Security is your top priority.
• The door sees frequent daily use.
• You want the strongest mechanical construction available.

Grade 2: Residential Security

Grade 2 locks meet slightly lower testing requirements but remain an excellent choice for most homes.

Many well-known residential smart locks fall into this category because they balance security, durability and cost.

For the average homeowner, a Grade 2 lock from a reputable manufacturer offers more than enough protection when paired with a solid door and reinforced frame.

UK & Insurance Standards

UK security standards focus on attack methods commonly used against British doors and locking systems.

Unlike ANSI testing, these standards take account of issues such as lock snapping, cylinder attacks and insurance compliance.

If you’re buying high security front door locks for a UK property, these are the certifications worth checking.

TS007 3-Star Rating

TS007 is one of the most recognised standards for euro cylinders.

It was introduced after lock snapping became one of the most common methods of forced entry through uPVC and composite doors.

A TS007 3-Star cylinder includes built-in protection against snapping and other common attacks. During testing, cylinders must continue protecting the lock even after part of the cylinder has been deliberately broken away.

Also note that: For most homeowners replacing an older euro cylinder, upgrading to a TS007 3-Star model is one of the simplest security improvements available.

Sold Secure Diamond/Gold

Sold Secure is an independent testing organisation widely recognised by insurers and police-backed security initiatives.

Products undergo physical attack testing using tools commonly carried by burglars.

For door locks you’ll normally encounter:

• Sold Secure Gold for high residential security.
• Sold Secure Diamond for products offering the highest level of resistance.

Although Sold Secure is better known for bicycle locks and security products, its approval provides additional confidence when comparing premium exterior locksets.

BS EN 1303

BS EN 1303 applies specifically to lock cylinders.

Instead of giving a simple pass or fail result, it scores cylinders across several performance categories, including:

• Durability
• Key security
• Corrosion resistance
• Drill resistance
• Attack resistance

Keep in mind: Many premium euro cylinders display both BS EN 1303 certification and TS007 approval because the standards measure different aspects of performance. If you’re replacing a cylinder, seeing both certifications is a good sign.

BS3621 (Mortice Locks)

BS3621 remains one of the most important standards for timber front doors.

It applies primarily to thief-resistant mortice locks and has been recognised by UK insurers for decades.

A BS3621 lock must pass tests covering:

• Resistance to forced entry
• Durability
• Bolt strength
• Lock operation
• Key security

Note: If your insurer specifies a BS3621 lock and your door doesn’t meet that requirement, any future claim following a burglary could become more complicated. Before replacing an older mortice lock, check your policy documents or contact your insurer to confirm which standard they require.

Key Security Features

When you’re comparing the best locksets for exterior doors, it’s easy to get distracted by long feature lists. Manufacturers love advertising fingerprint readers, mobile apps and voice control because they’re easy to demonstrate. Those features have their place, but they shouldn’t drive your decision.

Start with physical security. A lock that’s resistant to snapping, drilling and picking will protect your home even if the batteries die or your Wi-Fi goes offline. Once you’ve found a mechanically strong lock, you can decide whether smart features like biometric access, guest codes or activity logs are worth paying for.

Think of it as two separate layers.

• Physical protection defends the lock against forced entry and common burglary techniques.
• Digital functionality changes how you unlock, monitor and manage the door every day.

The best front door locks combine both. They offer strong mechanical protection first, then add smart features that make access easier without compromising security.

Physical Protection

Mechanical strength still matters more than smart features.

A fingerprint reader is convenient, but it won’t stop someone attacking a weak cylinder with basic tools. Always start with physical security before comparing digital functions.

Anti-Snap Points

Lock snapping remains one of the quickest ways to defeat older euro cylinders.

Burglars apply force to the exposed section of the cylinder until it breaks, allowing them to manipulate the locking mechanism inside.

Anti-snap cylinders are designed to fail in a controlled way. If someone attempts to snap the cylinder, a sacrificial section breaks away while the locking mechanism remains protected inside the door.

For uPVC and composite doors, this is one of the most valuable upgrades you can make.

Anti-Drill Plates

Some burglars try drilling directly into the lock to destroy internal pins or reach the cam mechanism.

High-security cylinders reduce this risk by using hardened steel inserts or rotating anti-drill pins. These components wear down drill bits and make attacks slower and much more difficult.

Also remember: The extra protection is especially valuable for front doors that aren’t visible from the street, where intruders have more time to work.

Pick-Resistant Features

Traditional pin tumbler locks can sometimes be manipulated with lock-picking tools.

Premium cylinders use features such as:

• Security pins
• Mushroom pins
• Sidebars
• Additional locking elements

These increase the number of movements required to pick the lock successfully and make common picking techniques far less effective. For most homeowners, lock snapping remains a greater concern than lock picking. Still, good pick resistance adds another layer of protection.

Reinforced Strike Plates

Even the strongest deadbolt depends on the strike plate holding firm.

Many standard strike plates are fixed with short screws that only grip the door frame. Under heavy force, the screws pull out long before the lock itself fails. Replacing them with reinforced strike plates secured by long screws into the structural timber strengthens the entire door assembly.

It’s an inexpensive upgrade and one that’s often overlooked. A premium lock fitted to a weak frame won’t perform as intended.

Digital Functionality

The better systems of smart locks combine convenience with practical security features that reduce the chances of forgotten keys, accidental lockouts or unauthorised access.

Not every feature will matter to every homeowner. If you’re buying one of the best front door locks UK retailers sell, focus on the functions you’ll use every week rather than the longest specification sheet.

Biometric Fingerprint Access

Fingerprint recognition has become one of the most popular alternatives to physical keys.

Instead of entering a PIN or unlocking the door with an app, you simply place your finger on the scanner. Most premium models store several fingerprints, allowing every member of the household to have their own profile.

The biggest advantage is speed.

There’s no phone to unlock, no code to remember and no key to search for when your hands are full. Modern sensors usually recognise authorised fingerprints in under a second.

Look for locks that offer:

• Encrypted fingerprint storage
• Multiple user profiles
• A physical key backup
• Alternative unlocking methods if the sensor fails

Keep in mind that: Fingerprint readers work best when they’re kept clean. Dirt, heavy rain or damaged skin sometimes reduce recognition accuracy, which is why reputable manufacturers always include another way to unlock the door.

Geofencing Proximity Unlocking

Geofencing uses your phone’s location to determine when you’ve arrived home.

Instead of opening an app every time you reach your front door, the lock recognises that you’re nearby and prepares to unlock automatically once you’re within Bluetooth range.

This feature works particularly well if you regularly arrive carrying shopping bags, luggage or children.

You still control how the lock behaves. Most apps let you decide:

• How close you need to be before the lock activates
• Whether the door ulocks automatically or waits for confirmation
• Which family members have access
• Whether the lock should secure itself again after you leave

Because geofencing relies on your smartphone, it works best when location services remain enabled.

Decoy PIN Codes

Some smart locks include a feature called a decoy PIN or fake PIN.

Here’s how it works.

Instead of entering your actual code by itself, you add extra random numbers before or after it. The lock ignores those additional digits and only reads the correct sequence.

For example:

Actual PIN:
2580

Accepted entry:
7412580936

Anyone watching from nearby sees a much longer number, making it far harder to identify your real access code. It’s a small feature, but it reduces the risk of someone learning your PIN simply by watching you unlock the door.

Temporary Guest Access

Digital access is one of the biggest advantages smart locks have over traditional locksets. Instead of cutting spare keys, you create temporary digital credentials.

You might give:

• A cleaner access every Tuesday morning
• A dog walker access during weekdays
• A delivery driver one-time entry
• Holiday guests access for the duration of their stay

When access is no longer required, you remove it from the app. There’s no need to collect keys or replace locks because someone forgot to return one.

Interesting to know: If you manage an Airbnb or short-term rental, this feature alone often justifies the cost of upgrading to a smart lock.

App-Based Activity Logs

Most connected smart locks record every locking and unlocking event. Open the app and you’ll usually see:

• Who unlocked the door
• Which method they used
• The exact time
• Whether the door was locked afterwards

This isn’t about surveillance. It’s practical.

You can quickly check whether your children arrived home from school, confirm that a contractor left the property and locked the door, or make sure you didn’t forget to secure the entrance before leaving for work.

Note: Premium systems also send notifications whenever someone unlocks the door or when the lock detects unusual activity.

Auto-Lock Timers

Everyone forgets to lock the front door occasionally. Auto-lock timers remove that risk by locking the door automatically after a preset delay.

Depending on the manufacturer, you might choose:

• 30 seconds
• 1 minute
• 3 minutes
• 5 minutes
• Custom schedules

Some locks also use door sensors to confirm the door has fully closed before engaging the deadbolt. This matters because locking a deadbolt against an open door serves no purpose.

For most households, automatic locking is one of the most useful smart features available. It works quietly in the background and reduces the chance of leaving your home unsecured.

Top Product Picks

Choosing the best locksets for exterior doors is about matching the lock to your door, the level of security you need and how you use your entrance every day.

Some homeowners want the strongest mechanical lock available. Others prefer fingerprint access or remote control through a smartphone. There isn’t a single product that’s right for everyone.

Avocet ABS High Security Cylinder

Best for: Upgrading the security of an existing uPVC or composite door.

Typical price: Affordable to mid-range

Replacing an old euro cylinder often provides more security than replacing the entire locking mechanism.

The Avocet ABS cylinder has become one of the best-known anti-snap cylinders in the UK thanks to its layered approach to physical protection. Rather than relying on a single security feature, it combines several attack-resistant technologies inside one cylinder.

Main features

• TS007 3-Star rating
• Anti-snap design
• Anti-pick protection

Limitations

• Overkill for most homes
• Limited smart functionality

Note: For business premises, reliability often matters more than connected features. That’s where commercial hardware still has an advantage.

Leading Manufacturers

Choosing a trusted manufacturer doesn’t guarantee you’ll get the best lock, but it usually improves your chances. Established brands invest more in testing, security certifications and long-term support than unknown manufacturers selling similar-looking products online.

Here are the brands worth considering when comparing the best locksets for exterior doors.

Leading Manufacturers

Choosing a trusted manufacturer doesn’t guarantee you’ll get the best lock, but it usually improves your chances. Established brands invest more in testing, security certifications and long-term support than unknown manufacturers selling similar-looking products online.

Here are the brands worth considering when comparing the best locksets for exterior doors.

Schlage

Schlage has been manufacturing door hardware for more than a century and remains one of the best-known names in mechanical and electronic locks.

The reputation comes from solid engineering rather than flashy marketing. Many of its premium deadbolts achieve ANSI Grade 1 certification, making them suitable for demanding residential and commercial use.

Schlage products are best known for:

• Mechanical reliability
• Heavy-duty deadbolts
• Keypad locks
• Commercial hardware

Although the company focuses primarily on the North American market, several products remain popular among UK buyers looking for premium deadbolt systems.

Yale

Yale is one of the oldest lock manufacturers in the world and arguably the most recognisable name in the UK market.

Its range covers almost every category of exterior door security, including:

• Mortice locks
• Night latches
• Euro cylinders
• Smart locks
• Key safes
• Window security

Yale has also expanded aggressively into connected home technology. Products like the Assure Lock 2 and Yale Linus series compete directly with brands such as Nuki and August.

Keep in mind: If you’re buying your first smart lock, Yale is usually one of the safest places to start because of its broad compatibility with Apple HomeKit, Google Home and Amazon Alexa.

Kwikset

Kwikset has built a strong reputation in North America by offering residential locks that balance affordability with practical security.

The company specialises in:

• Deadbolts
• Smart locks
• Fingerprint locks
• Electronic keypads

Its Halo range has become particularly popular because many models connect directly to Wi-Fi without requiring an additional hub in the future of smart home.

Note: UK buyers should remember that some Kwikset products are designed around American door dimensions. Always check compatibility before ordering.

August

August focuses almost entirely on retrofit smart locks.

Instead of replacing your existing lockset, most August products fit to the inside of your current door, allowing you to keep your original keys while adding smartphone control and automation.

The brand stands out for:

• Easy installation
• Strong mobile app
• Reliable auto-unlock
• Guest access management

If your existing mechanical lock already provides good security, a retrofit design like August often makes more sense than replacing everything.

Avocet ABS

Avocet specialises in high-security lock cylinders for UK homes.

Its ABS range became well known after anti-snap protection became a major concern for uPVC and composite doors.

The company focuses on:

• Euro cylinders
• Anti-snap technology
• TS007-certified products
• Replacement cylinders

For many homeowners, upgrading to an ABS cylinder offers one of the highest security improvements per pound spent.

ERA

ERA has supplied locks to the UK market for decades and offers one of the widest catalogues available.

Its range includes:

• Night latches
• Mortice locks
• Euro cylinders
• Window locks
• Multipoint hardware
• Smart security products

Many ERA locks meet the standards required by UK insurers, making them a dependable choice for replacement hardware.

Probrico

Probrico targets buyers looking for affordable door hardware without moving into premium commercial pricing.

Its catalogue includes:

• Entry handles
• Deadbolts
• Lever sets
• Electronic locks
• Interior hardware

While the brand doesn’t have the heritage of Yale or Schlage, it provides a wide selection for homeowners working within a tighter budget.

Selection Criteria

Before comparing features or prices, confirm that the lock is physically compatible with your door. Measurements, construction and existing hardware all influence which products you can install.

The following checks help avoid expensive returns and installation problems.

Backset Measurement (2-3/8 vs 2-3/4)

The backset is the distance from the edge of the door to the centre of the keyhole or spindle.

On American deadbolts, you’ll commonly see two sizes:

• 2⅜ inches (60 mm)
• 2¾ inches (70 mm)

Many adjustable deadbolts fit both measurements, but not all do. If you’re replacing an existing lock, measure before ordering rather than assuming the new lock will fit.

Also note that: For UK doors using mortice locks or multipoint systems, manufacturers often specify different measurements altogether, so always check the product documentation.

Door Thickness Compatibility

Door thickness affects both security and installation. Most residential locksets fit standard doors, but thicker timber doors, insulated composite doors and commercial entrances often require longer fixing screws or extended cylinders.

Before buying, measure:

• Door thickness
• Existing cylinder length
• Backset
• Handle centres (for multipoint doors)

A lock designed for a thinner door may leave exposed threads or prevent the cylinder from operating smoothly.

Smart Home Integration (Alexa/Siri)

A smart lock is only as useful as the ecosystem around it. If you already use Amazon Alexa, Google Home or Apple HomeKit, choosing a compatible lock lets you manage your front door alongside lights, cameras, alarms and routines. If you don’t use a smart home platform, paying extra for advanced integrations often isn’t worth it.

Before buying, check whether the lock supports your preferred platform natively or whether you’ll need an additional hub or bridge.

Here’s what the main platforms offer.

Some manufacturers advertise compatibility with every platform, but the available features aren’t always the same.

For example, one lock might support voice locking through Alexa but not voice unlocking, while another supports Apple Home Key but not Google Home. Reading the compatibility list before you buy saves disappointment later.

If you’re building a smart home from scratch, look for products that receive regular firmware updates. Smart locks last much longer than smartphones, so ongoing software support matters almost as much as the hardware.

Battery Life & Backup Keys

Battery-powered locks are reliable, but they aren’t maintenance-free. Most smart locks run on AA batteries, with battery life ranging from six months to more than a year depending on usage, Wi-Fi activity and motor strength.

Frequent remote access, activity notifications and Wi-Fi connectivity usually shorten battery life compared with Bluetooth-only models.

Fortunately, running out of power rarely leaves you locked outside.

Most quality smart locks include one or more backup options:

• Physical key override
• Emergency USB power connection
• Replaceable batteries without removing the lock
• Low-battery notifications through the companion app

Many locks begin warning you weeks before the batteries become critical, giving you plenty of time to replace them.

Remember: As a general rule, replace batteries once a year rather than waiting for the warning. It’s inexpensive, takes a few minutes and removes one less thing to worry about.

Which Lockset Is Best for Your Exterior Door?

The best locksets for exterior doors depend as much on the door itself as the lock. Choosing the right combination gives you better security, smoother operation and fewer installation problems.

Remember: If your current lock works well but the cylinder is outdated, replacing only the cylinder often provides better value than replacing the complete lockset.

Common Mistakes When Buying Exterior Door Locksets

Many lock replacements happen because the original lock has worn out. That’s understandable. But replacing it with the same model isn’t always the best decision.

These are the mistakes homeowners make most often.

Buying the Wrong Lock for the Door

Deadbolts, mortice locks and multipoint systems aren’t interchangeable. Always identify your existing locking system before ordering replacement hardware.

Ignoring Security Certifications

A lock might look solid and still fail basic attack tests.

Look for recognised standards such as:

• TS007 3-Star
• BS EN 1303
• BS3621
• Sold Secure
• ANSI Grade 1 or Grade 2

Independent testing tells you far more than product descriptions.

Measuring Incorrectly

Cylinder length, backset and door thickness all affect compatibility. Even a high-quality lock becomes difficult to install if the measurements don’t match your existing door.

Measure first. Order second.

Paying for Features You’ll Never Use

Fingerprint readers, Wi-Fi control and voice assistants sound appealing, but they aren’t essential for everyone. If you rarely use smart home devices, a high-quality mechanical lock may be a better investment than an expensive connected model.

Spend your budget on security before convenience.

Final Thoughts

Choosing the best front door lock isn’t about buying the newest product or the most expensive one. It’s about matching the lock to your door, your existing hardware and the level of security your property needs.

If you own a timber property, a certified mortice lock remains one of the strongest options. For composite and uPVC doors, upgrading to a high-security euro cylinder or a compatible smart multipoint lock often delivers the biggest improvement without replacing the entire door. If convenience matters as much as security, today’s smart locksets combine proven mechanical protection with features such as fingerprint access, temporary digital keys, remote management and activity logs.

Whatever you choose, take accurate measurements before ordering, check the relevant security certifications and buy from a manufacturer that offers products designed for your door type, ongoing software support where applicable and a solid warranty. A well-chosen lockset should provide reliable security for many years while making everyday access simpler.
