Good to know
  • It replaces a euro profile cylinder on an aluminium or wooden door, and the backset (keyhole centre to door edge) must be at least 30 mm.
  • Only the included keypad is rated weatherproof (IP55); the cylinder itself has no stated weather rating.
  • The two 18650 batteries are rechargeable and last 8–12 months; the lock warns you when they drop below 7.2 V.
  • The cylinder itself unlocks by Bluetooth or the emergency key; fingerprints and passcodes need the included keypad, Alexa and Google Home the WiFi bridge.

Before you buy Every worry, handled.

The questions everyone asks, answered plainly, because peace of mind starts before you buy.

What's the app?

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

What happens if I lose my physical key?

For security purposes, our physical keys are designed unique to your lock ID, and we do not have spares of their respective physical keys. We recommend keeping a key with a trusted family member from the first day. The lock can still be unlocked via other means based on your lock model, i.e. smartphone unlock, fingerprints, pin codes, etc

The touchscreen of the lock seems reflective. Can fingerprints be left on the lock, making it easy to guess the password?

Simpled locks come with an imaginary PIN code feature that allows you to enter other digits before/after your actual PIN. This is optional but will help to deter hackers and prevent your PIN code from being exposed. Also, with the security lockout mode, it is even more difficult to guess your PIN code.

Why should I buy an electronic door lock?

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 are already at your gate. Wouldn’t it be nice if they can 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/pin codes and even your smartphone).

Why can't the app be locked after I have completed the installation?

Please check if the door opening direction settings are correct.

Your question not here? Call +44 20 7096 0094 (Monday to Friday, 9am to 5pm) or send us a photo.
