The Cisa C3000 cam lock offers the perfect balance between safety against attacks, protection against key duplication and fewer keys to manage accesses. Micro-switch terminals have to be welded on and allows for automatic return to key extraction position. It has a Bump Key Power (BKP) device and a special spring thereby making it highly resistant to bumping and wax impression burglaries. The Cisa C3000 cam lock is supplied with 3 keys, fixing screws and a security card which can be used to control duplication of keys. The card should be presented in order to duplicate a key.
