Why Choose Mul-T-Lock?
Mul-T-Lock is manufactured of case hardened and tempered alloy steels that are
maunfactured with the highest quality construction. Using a unique system of 
telescopic tumblers and meeting both the rigid German burglary standard and the USA burglary standard UL-437.
These rigid standards result in lock systems that offer the following: key control, pick resistance, drill resistance, saw resistance, bolt cutter resistance, bump key resistance, rust resistance, and restricted key duplication.

Key Control
With Mul-T-Lock Interactive products, you have the highest level of Key Control. When planning a new project, key control is often overlooked but can become very costly after completion. We represent the world leader in high security lock cylinders with totally restricted keys that retrofit your new or existing hardware. From construction to completion, all your master key and key control problems are eliminated.

Orders for our restricted keys which are stamped "Do not 
duplicate" will be made only upon presentation of a signed 
key card and signature verification. A special factory 
authorized high security key machine is needed to cut 
these keys. Always sign the key card immediately upon 
purchase. Signed key cards will have the signature verified 
when ordering new keys. Full information about the
Restricted Key Cutting Procedures can be obtained 
through Mul-T-Lock® professional dealers.

Master Key Systems
In a Master Key System, one Master Key operates all the locks in the system, while other keys can only open specified locks. Mul-T-Lock products may be master keyed using the hierarchical (flow chart) method or the matrix (key user chart) method. One major advantage to Mul-T-Lock master key systems is the pick resistance of the cylinders. Normal master key systems become easier to pick as more master wafers are added thus diminishing your security. This does not happen with Mul-T-Lock, so you have security, key control, and the convenience of master keys.

secure.
