Enhanced key copy control

Mul-T-Lock takes every possible measure to reduce unauthorized key duplication.

The MTL™800 key copy control system is employed through a unique card with a magnetic strip that holds your unique, encrypted key code. The key cutting control card, when presented to a Mul-T-Lock authorized locksmith, grants its holder the ability to order additional keys.

The certified key cutting procedure can only be implemented when the original magnetic card is presented to an authorized Mul-T-Lock dealer who owns a KC5 key cutting machine.
