Electronically controlled, changeable lock with dead bolt.
Approx. 390,000 theoretical variations.
The user key gives via an internal microswitch a start signal for the external control system. Depending on the external control system different release functions (e.g. time delay, dual mode, remote release) can be realised.
In version 70171 Varios E the key is retained when the lock is opened. The change to a new key will be initiated via a slide unit at the back of the lock.
