MUL-T-Lock Interactive + Thumbturn/High Security Cylinder Lock, Nickel

Mul-T-Lock's High Security cylinders feature a special telescopic pin tumbler mechanism with internal and external pins. To enable the plug to rotate, both the internal and external shear lines must be aligned simultaneously. The patented Mul-T-Lock plug has a unique structure, where a three-dimensional shear line is formed when the top and bottom pins, plug, and body meet, creating an almost perfect spherical shape. Steel inserts enhance the cylinder's anti-drilling resistance, providing an added security dimension and amplifying the pick-and-drill resistance for High Security needs.

When master keyed, additional side pins or back pins can be incorporated. The Interactive system combines the special telescopic pin tumbler mechanism and features of the Classic system with a spring-loaded pin in the cylinder plug to produce a 'virtual combination' only when the key is inserted in the lock. The Interactive patented key and key blank offer increased control over key cutting, achieving an even higher level of key security.

Additional keys are cut after presenting a Mul-T-Lock key card and verifying the customer's identity in accordance with Mul-T-Lock key cutting procedures, which can be obtained through professional Mul-T-Lock locksmiths. The Interactive technology is retro-compatible with the Mul-T-Lock Classic system, allowing existing locks to be upgraded.

Mul-T-Lock Interactive+ is a High Security cylinder lock with a thumbturn, featuring 3 keys and a keycode card. The lock pictured is size 40/40.
