Mul-T-Lock, an ASSA ABLOY company, is famous for its high security protected key systems. The patented Interactive key system raises the level of security to new heights. The Interactive system combines the unique telescopic pin tumbler mechanism and special 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.

This massive 14mm (9/16") thick shackle lock, with 57mm (2 3/16") clearance, is available in KD (Keyed Different), KA ( Keyed Alike) or MK (Master Keyed) version. Part of the high security of Mul-T-Lock is is that keyed alike sets always have unique key numbers (versus selling from a large batch of KA locks). This means, however, that all KA or MK sets are special ordered and have, on average, a 5 day shipping delay.
Standard amount of keys per lock or KA lock set is 2 and one key code card.
