The Interactive+ is a dimple lock made by Mul-T-Lock. The Interactive+ is a telescoping dimple design that uses 5 inner and 5 outer pin pairs. The key raises both the inner and outer pins to the shear line. The Interactive+ also uses a moving element in the key to raise a pin stack higher than physically possible by a traditional key, similar to the Mul-T-Lock Interactive.

The Interactive+ supercedes the Mul-T-Lock Interactive and has since been superceded by the Mul-T-Lock MT5/MT5+. The Mul-T-Lock CLIQ is an electomechanical lock that uses a modified Interactive cylinder with a sidebar and electronic components. The Mul-T-Lock 3-in-1 is a construction keying system that uses Classic and Interactive cylinders with modified plugs and inner pins.


Principles of operation

The Interactive platform brings support for back and side pins. It has hardened steel inserts to prevent drilling and uses telescopic pins to increase the difficulty of picking the lock. Mul-T-Lock uses security pins to further increase the security of the lock.

Mul-T-Lock Keys are noticeably different from pin-tumbler keys due to the mechanism of the lock. It is similar to the Mul-T-Lock Classic but with the addition of a moving component inside the key used to deter unauthorized key duplication. In the Interactive+, the moving element in the key interacts with a passive pin which extends through the bottom of the plug into a divot in the shell, and is lifted as the plug is rotated. This lifts the element in the key, which can in turn lift the associated key pin to a level higher than maximum lift. Due to the differing shapes of the interactive element, keys for the Mul-T-Lock Interactive and Interactive+ are not interchangeable.
