Mul-T-Lock implements strict key control procedures to protect against unauthorized key duplication.
All Mul-T-Lock cylinders come with a card that is necessary for key duplication.
The proper name for this item is a Mul-T-Lock "Key Order Card".
This is an authorization card that resembles a credit card in appearance, and serves the purpose of proving that you are authorized to obtain duplicate keys.
Anyone attempting to make keys without possession of this Key Order Card will be refused.
So you can rest assured that Mul-T-Lock’s high security protection covers all the bases – offering strength, durability, superior pick and drill resistance and ultimate key control with every cylinder.
