High security Mul-T-Lock locks

Mul-T-Lock locks are part of a line of superior high security products. They are designed to ensure your security and peace of mind. The Mul-T-Lock provides all the benefits of a high security lock.

Depending on the choice of model, their locking mechanism provides a triple, double or standard level of security.

In addition to its triple security design, which makes it a non-pickable lock, it provides enhanced key control with patented keys and the requirement to present a control card to the authorized locksmith for duplicate keys by Mul-T-Lock’s specialized cutting equipment.


The Mul-T-Lock Dual Security Lock is the Interactive+ lock. Like the MT5+, it provides a solution for applications requiring physical security and protection against unauthorized key duplications.
