High precision “KRAB” type locking devices ensure locking in three directions (top, bottom, left/right side) via system of latches (11 latches and 1 internal latch). A locking device is reprogrammable and goes with 8 laser cut keys. Two of them are meant for use by installers during mounting or repair. One of the remaining 6 keys is used to reprogram locking device (master key); the rest are meant for regular use by owners after reprogramming

In order to reprogram the locking device it is necessary to insert the reprogramming key from outside and make two full 360° turns (repeat the operation from inside). The locking device reprograms automatically after this operation
Three types of keys are used:

• Keys to be used during mounting (2 pieces, not packed);
• Master (reprogramming) key (1 piece, has distinct colour and profile);
• Regular keys (5 pieces, packed)

How to use:

Special keys must be used during mounting and repair. After the activities are over you can reprogram locking device by locking and unlocking it once using master key. The keys used during mounting become unusable after that: regular keys and master key can only be used.
