Mul-T-Lock’s patented High Security Interactive platform raises the user’s level of security to new heights, thanks to several special features:

  • A spring-loaded pin placed inside the cylinder plug, which produces a “virtual combination” when the key with the floating pin is inserted.

  • Mul-T-Lock’s unique telescopic pin tumbler mechanism, with internal and external pins – requiring the simultaneous alignment of both internal and external shear lines for the plug to rotate.

  • A specially designed plug, which forms a spherical, 3-dimensional shear line with the top and bottom pins, within the cylinder body.

  • Key limitation is ensured by the patented key and key blank, supplied together with a coded Mul-T-Lock key card in every Interactive package. Additional keys may be cut by authorized Mul-T-Lock dealers, upon presentation of the key card – in accordance with Mul-T-Lock’s official key cutting procedures.

  • Steel inserts with high drill resistance

  • High pick and bumping resistance

  • Optional side and back pins, specially suited for master key systems.
