1. Mul-T-Lock®’s High Security Interactive® cylinders have a special telescopic pin tumbler mechanism with internal and external pins. Both the internal and external shear lines must be aligned simultaneously in order for the plug to rotate.

2. The Interactive system combines this special telescopic pin tumbler mechanism with a spring-loaded pin in the cylinder plug to produce a ‘virtual combination’ that may only be acheived when the key is inserted in the lock.

Additional Features The patented Mul-T-Lock plug has a special structure. When the top and bottom pins, plug and body meet, a three-dimensional shear line is formed, creating an almost perfect spherical shape. Steel inserts enhance anti-drilling resistance

These features provide an added security dimension, amplifying the Mul-T-Lock cylinder’s pick- and drill-resistance for High Security needs. When master keyed, additional side pins or back pins can be incorporated.

Patented key control with Special authorization card
The Interactive patented key and key blank provide increased control over key cutting to achieve an even higher level of key security. Additional keys are cut after presentation of a Mul-T-Lock key card and verification of customer identity in accordance with Mul-T-Lock key cutting procedures, which may be obtained through professional Mul-T-Lock locksmiths.

Interactive technology is retro-compatible with the Mul-T-Lock Classic system, allowing existing locks to be upgraded.
