The double bitted model comes with an innovative, patented system of recoding through a metallic “SIM”.
You can replace the coding card of the key (from the internal side of the door), without the need of a screwdriver and without replacing the escutcheon.
An extremely easy, quick and “do-it-yourself” system that will allow anybody, at any time, changing the combination of the lock, when needed and without calling skilled staff. The gear mechanism assures a silent and soft movement.
The lock is protected by a manganese steel plate. An installation key is supplied.
You can add to this lock an extra service cylinder lock.
