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  the 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, they are not duplicatable and we cannot provide replacement or spare keys. We recommend keeping a key with a trusted family member from the first day. The lock can still be unlocked via other means dependent on your lock model, i.e. smartphone unlock, fingerprints, pin codes, etc

My batteries have completely run out. What can I do?

There are two solutions: Physical Keys Physical keys are provided together with Simpled smart locks, which ensures that you will still be able to enter the house mechanically even if its batteries run out. It is strongly recommended to keep at least one spare key on you or a family at all times for such situations. USB Input Also, when the physical key is not available, there is a USB input on the bottom part of the smart locks (besides the key input) that enables you to connect a power bank to wake up the lock and unlock it.

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 these things, it may be time you installed an electronic door lock. With a smart door lock, you will be able to open your gates without using keys (fingerprint/RFID tag/pin codes and even your smartphone).
