The Cisa Cambio Facile 6 Lever Electric Lock allows you to replace keys without having to dismantle the lock or any part of it, and using only a special tool and keys. It features 4 crossbars (deadbolts) and an electronically operated latch which are both made from high resistance zinc plated steel. The lock protects against tampering and picking tools and is active on all six levers of the lock to provide greater protection against forced entry with picking tools.
