For many homeowners, smart locks represent a new level of home automation that promises enhanced security and ease of access.

However, with the rise of smart technology, new security concerns also emerge. While smart locks offer greater control and convenience, they aren’t immune to vulnerabilities. As these locks are connected to the internet and integrate with your home network, smart lock security issues have become a topic of growing concern.

In this article, we’ll explore the potential security issues with smart locks and how you can protect your home from these risks. Whether you’re considering installing a smart lock or already using one, it’s important to understand these risks and how to mitigate them to ensure the safety of your home.

The Growing Popularity of Smart Locks

Convenience Meets Security

The appeal of smart locks is undeniable. Gone are the days of fumbling for keys or worrying about lost duplicates. With a smart lock, you can:

• Remotely control access: Lock and unlock doors from anywhere using your smartphone or app.

• Set temporary access codes: Perfect for guests, service personnel, or housekeepers.

• Monitor activity: Receive notifications about who is entering or exiting your home.

• Integrate with other smart devices: Smart locks often work with home security systems, cameras, and even voice assistants like Amazon Alexa or Google Assistant.

However, these conveniences come with certain risks. The reliance on smart lock technology can expose you to vulnerabilities that traditional locks don’t face. So, while the future looks bright for keyless entry, it’s important to evaluate potential smart lock security issues thoroughly.

Common Smart Lock Security Issues

1. Vulnerabilities in Software and Firmware

One of the primary concerns when it comes to smart lock security is the software that powers these devices. Smart locks, like any other connected device, rely on software that can have bugs or security flaws. These flaws can leave your smart lock susceptible to attacks.

How Software Vulnerabilities Work

• Firmware Exploits: Hackers may exploit vulnerabilities in a smart lock’s firmware to bypass security measures and gain unauthorized access. Manufacturers regularly release firmware updates to patch these security holes, but not all users keep their devices up-to-date.

• Weak Encryption: Encryption is crucial for securing communications between your lock and the connected app. If a smart lock uses weak or outdated encryption, attackers can intercept data, such as access codes or lock status, and manipulate it for malicious purposes.

How to Mitigate This Risk:

• Ensure that your smart lock receives regular software updates from the manufacturer.

• Check that the smart lock uses strong encryption methods, such as AES-128 or better.

2. Hacking and Remote Attacks

Another serious smart lock security issue involves remote hacking. Many smart locks connect to your home’s Wi-Fi or a Bluetooth network, allowing you to control them from anywhere. However, this wireless communication can be intercepted by hackers if not properly secured.

How Remote Attacks Work

• Wi-Fi and Bluetooth Vulnerabilities: If a smart lock is poorly configured or lacks strong encryption, hackers can potentially gain access remotely via Wi-Fi or Bluetooth. For example, Wi-Fi-connected locks might be targeted by attackers using advanced techniques like brute force or credential stuffing to guess your access password.

• Weak Passwords and Default Settings: Many smart locks are installed with factory default passwords, which are often easy for hackers to guess. If users fail to change these defaults, their locks are at risk.

How to Mitigate This Risk:

• Always change default passwords and use strong, unique passwords for both your smart lock and the associated app.

• Enable multi-factor authentication (MFA) where available, which adds an additional layer of security beyond just a password.

3. Bluetooth and Signal Interference

Bluetooth-enabled smart locks rely on short-range wireless technology to communicate with your smartphone or other devices. While Bluetooth is generally considered secure, it can still be susceptible to interference and exploitation.

How Bluetooth Attacks Work

• Bluejacking and Bluesnarfing: These are attacks that exploit Bluetooth connections to send unsolicited messages or gain unauthorized access to devices. While rare, these attacks can compromise the security of Bluetooth-enabled smart locks.

• Signal Interference: In some cases, the Bluetooth signal can be jammed or blocked, preventing you from using the lock when you need it. This can be a serious inconvenience if you’re locked out of your home.

How to Mitigate This Risk:

• Keep your Bluetooth connections secured and limit pairing to trusted devices only.

• Regularly check that your smart lock’s Bluetooth function is updated with the latest security protocols.

4. Physical Access and Bypass Techniques

Though smart locks are designed to be more secure than traditional locks, they’re not immune to physical attacks. Some hackers or burglars may attempt to bypass the lock mechanism itself, especially if they have physical access to the door.

How Physical Bypass Works

• Lock Picking: Even though many smart locks are resistant to traditional picking techniques, some cheaper models may still be vulnerable to lock picking or bypass methods.

• Battery or Power Failures: Many smart locks rely on batteries, which can fail over time. If someone manages to remove or disable the power source, they may be able to gain access.

How to Mitigate This Risk:

• Use a high-quality smart lock that includes tamper detection and anti-picking features.

• Regularly check and replace the batteries to ensure your lock remains operational at all times.

5. Privacy Concerns with Data Storage

Smart locks collect data to function effectively, such as who is entering or leaving the house, and when. However, this data can be a potential security risk if not properly protected.

How Data Privacy Issues Arise

• Data Breaches: If a smart lock’s manufacturer suffers a data breach, hackers could gain access to sensitive information, such as your access logs or PIN codes.

• Cloud Storage Risks: Many smart locks store data on the cloud. While this offers convenience, it also introduces a risk if the cloud server is compromised.

How to Mitigate This Risk:

• Choose smart locks from reputable manufacturers with strong privacy policies and encrypted data storage.

• Limit the amount of data stored in the cloud, and consider using a local storage option if available.

Everyday Frustrations Driving Smart Lock Adoption

One reason smart locks are becoming popular across UK homes is the frustration people face with traditional keys. Losing keys often means changing the entire lock, which can be both costly and inconvenient. Carrying a bunch of keys is another annoyance, especially for busy families or landlords with multiple properties.

Smart locks like the Simpled SS Slim and SF Slim solve these issues by replacing keys with fingerprint, code, or app access. This not only eliminates the hassle of key management but also introduces features like remote control and temporary access codes—a game-changer for anyone managing cleaners, guests, or Airbnb rentals.

Battery Life and Power Outages: The Biggest Customer Concerns

For many homeowners considering smart locks, the first question is: What happens if the battery dies or the Wi-Fi goes down?

• Battery Worries: Smart locks are designed with long-lasting batteries. Simpled’s BLE-powered locks use ultra-low energy consumption, ensuring batteries can last months—even years—with normal use. Most models also provide low-battery alerts well in advance.

• Power & Wi-Fi Outages: If your Wi-Fi goes down, local features like fingerprint or code entry still work. And in the event of a complete power failure, most smart locks include a mechanical override key or an emergency charging port.

This reassurance is vital for homeowners and Airbnb hosts who need uninterrupted access at all times.

Smart Locks for Airbnb and Rental Properties

While most homeowners ask the same questions about smart locks, Airbnb hosts and landlords often highlight one specific challenge: reliable connectivity. If a property has unstable Wi-Fi, managing remote access can become tricky.

This is why many UK hosts prefer locks with offline-capable features (like PIN codes or fingerprint access) in addition to app control. Simpled’s range includes models designed for high-turnover use, making it easy to issue and revoke codes instantly—no need to meet guests in person.

Door Compatibility: A Step Often Overlooked

One of the most frequent issues raised by customers isn’t hacking—it’s door compatibility. UK homes often use multipoint locking systems, and not every smart lock fits directly.

Before purchase, always:

• Check the lock dimensions against your door.

• Verify if the lock supports multipoint mechanisms.

• Ask for professional installation advice if unsure.

At Simpled, we recommend a compatibility check for every new customer to prevent costly mistakes and ensure smooth installation.
