This 100 mm long model fits standard European locks (EURO profiles) and is designed for doors with a thickness of 40-50 mm.

Compatibility and easy installation

The cylinder is compatible with EURO-type locks, which means you don't have to replace the entire door cassette. Installation is just a matter of replacing the old cylinder and screwing in the new one - all you need is a hex key and a few minutes. The design allows for length adjustment with an internal knob.

5 unlocking methods

The Avatto lock offers five ways to open the door: fingerprint, PIN code, proximity card, mechanical key and TUYA smartphone app. This allows you to choose the most convenient option or grant access to different members of the household.
