The Mul-T-Lock patented interactive key and cylinder system raises the level of technology in high security locking to new heights.

The Interactive key system incorporates a high precision moving insert which interacts with a spring loaded pin in the cylinder plug to produce a “virtual combination” only when the key is inserted into the lock.

The Patented Mul-T-Lock key design provides increased control over key blanks, discouraging unauthorised cutting.

The Interactive system has a unique key registration card which sets it apart from other systems. Locksmiths will only cut replacement keys on production and verification of the registration card.
