Multifunction lock

CISA multifunction locks combine two locks, giving you increased security compared with standard locks for armoured doors and enabling you to safely manage third party access.

Resistance to forced entry.
Every lock has two different locks to make it more difficult to force entry.
In the double bitted key versions, the anti-picking system adds further protection against forced entry using traditional tools (Bulgarian method), thanks to 6 anti-friction levers controlled by independent springs.
In the cylinder versions, you can personalise your level of security using high secure cylinders and cylinder protective roses.

Security when keys are lost or stolen.
In the New Cambio Facile versions, the rekeyable system allows you to change the key you are using if it is stolen or lost with little inconvenience and as many times as you wish, without having to change the lock.

• Version with security function and dependent locks: the upper lock (secondary) blocks the lower lock when the latter is locked.
• Version with security function and independent locks: the key in the upper lock operates the latch bolt and the upper deadbolt and can be operated when the lower lock is open. The upper lock blocks the lower lock when the latter is locked.
• Version with service lock: the key in the upper lock operates the latch bolt and upper deadbolt.
• Version with service lock and opening limiting device:  the key in the upper lock operates the latch bolt and the upper deadbolt; the opening limiting device is activated by operating the first throw of the upper lock.
