PROTEC² CLIQ normal user key cylinder group is intended for cases where access rights are stable (e.g. grand master key) or changes are very rare. Changing the access rights for normal user key is done by changing electronical openings inside CLIQ locks via programming key, since there is no list of authorised locks on the key. Electrical openings in locks are defined in the locking planning software when the system is ordered and preprogrammed to the locks at the factory. Used in cylinder group systems. Patented PROTEC² (T) key system.
