FAQ

Why should I buy a smart cylinder?

A: We would like to counter-question some of your experiences with your own door locks. Do you remember a time when you forgot your keys and was locked out of your home?What happens when you arrive home late and depend on someone (parents/maid) in the house to open the door for you? Do you wake them up? You invited your best friends/family members to your house, but you were running late, and they were already at your gate. Wouldn't it be nice if they could enter your home instead of waiting aimlessly outside? Have any of your belongings been scratched/damaged through keys in the same bag/pocket? If you have experienced the above scenarios, it may be time you installed an electronic door lock. With an electronic door lock, you will be able to open your gates without using keys (fingerprint/RFID tag and even your smartphone).

Is it compatible with my door?

It's suitable for doors with a 60mm nightlatch. (Nightlatch NOT included).

Are batteries included?

Yes, A CR123A battery is Included, and an alert is given when the battery is running low.

What happens when the lock is out of battery?

In the event of the battery failing, there is a further fail-safe, thanks to a USB-C battery connection override.

Do I need the Simpled Gateway?

Without the need for a gateway, you have the convenience of sharing smartlock access with your smartphone. However, when combined with a Wireless Keypad and Gateway, you gain the ability to remotely share and delete passcodes for guests, cleaners, and repair services from anywhere in the world.

What happens when the battery is empty?

When the battery is low, an audible warning will sound when the lock is opened. There are still approximately 100 openings possible. When the battery is completely empty, you can use your power bank to wake up the lock and unlock it.

What if the smartphone I use to open the door runs out of battery charge?

There are several other ways you can unlock your lock, like fingerprint, proximity tags, remote control(optional).

If someone steals a family member's phone, can they get into my house?

If a smartphone is lost or stolen, it can be deactivated by the admin user. This means that security against unauthorised entry is still ensured without changing the lock.

Is this smart lock weatherproof?

Yes, it is.

How many guests can I have on my Smart Lock?

There is no limit to the number of guests associated with one lock.

Is the Simpled app free?

Yes. It can be downloaded and updated completely free of charge. The app is available for Android and iOS smartphones.

If I change my smartphone, do I lose the setting of the lock?

All your settings are on your password-protected accounts. So they are with you, wherever you go.

Are any electrical connections necessary to install an electronic cylinder?

No electrical connections to the door are needed as it is powered by long-life batteries. The user is warned when the battery charge is low by both the lock and app.

What if the battery runs out?

You can replace the batteries from the outside.

How long is the battery life of Simpled smart door lock?

The battery lifetime is about 8-10 months.

How long does delivery take?

My current cylinder is very close to the edge of the door. Can I install this smart cylinder on that?

From the outside, when the door is closed, please measure and ensure you have at least 2.5 centimetres between the centre of your current cylinder and door frame(NOT door edge, but door frame). We want to make sure the outer knob won't hit the door frame.Need more help? Reach us on Live Chat.

What door thickness does it support?

40mm to 70mm

How far away can the hub be?

It will be connected to the lock via Bluetooth. So it's ideally around 10 meters.However, the maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment.

Does it have NFC?

Not on all smartphones. Some are using encrypted NFC, and it won't be compatible with the lock. In some regions, people can pair transportation cards on their phones with the Simpled smart locks. In some other countries, it's not possible.

Isn't voice command on Alexa a bad feature? Anyone in my home has access to open the door?

That's the point. It's for easier access of the people inside. You trust them. Don't you? Even if you don't, there's a pin code that should be announced after a command, and that's what not everyone has!

I bought two different Simpled Smart locks for the entrance and my room. Can I use the same contactless fob(/phone tag) to unlock them both?

Sure. Simpled Tags can be programmed on all Simpled smart locks.

What's the app?

It's TTlock app. You can find it on both Google Play and App Store.

Absolutely first-class service from Simpled. I ordered a lock, and it was delivered the very next day. I carried out an installation of the lock the same day, and followed the guidelines and extremely easy-to-follow videos produced by Simpled. Installation was very easy on my multi-lock door. Setting up with the TT Lock app was […]

Sales enquiry by telephone was most helpful and provided the information I needed to make a decision on purchase and selection of the correct equipment. Installation was simple and could have been quicker but I was taking my time to get it right. I spent an hour installing and programming in total, but next time […]

Simpled are an excellent company selling a state of the art product. I looked for ages to find a door lock that could be locked automatically and opened remotely. It does just that.

Great products & great service! We love the keypad locks we purchased for two of our AirBnBs in our converted church! One of them stopped working and as it was still 1 week within the 2 year warranty, they honoured it and sent a brand new part the next day! Thank you so much :)

The regular nightlaches as long as they have a cylindrical part must be fine. But I highly recommend sharing some pictures with our support team to guide you properly.

If i have to buy a new night latch, do you have a list or recommendation for a night latch? I have a glass panels.pm my front door so doesn this work with a latch can be locked with a key internally (otherwise easy for a burglar to break the glass and turn the latch internally to open)

Please send us some pictures of your lock, our support team will check and answer your queries.
