TTLock System in Practice

On the outside of the door, there is a WK2 keypad – you enter the code, and the door opens. Instead of fumbling for keys, you can simply enter the assigned PIN, opening the door personally or sharing access remotely.

Users can also use the R1 remote control, which allows opening the door without approaching – e.g., from a car, reception, or an upstairs apartment.

On the inside of the door is the RX2052 lock, which can be opened manually with a knob, an IC card, or via the app.

For even faster and fully remote operation, the system can be supplemented with a TTLock Wi-Fi gateway, which enables instant data synchronization between the app and devices – without the need for physical proximity.

All system components – lock, keypad, remote control, and Wi-Fi gateway – are available in our assortment, and you can combine them as needed to create a configuration tailored to your requirements.

You can also expand the set with devices compatible with the TTLock app, such as wireless keypads, door locks, electronic padlocks, cabinet locks, or door cylinders.
