High Security reversible key with patented floating insert. Patented cylinder with telescopic pin tumblers.
Pick and drill resistant lock.
Durable nickel-silver and stainless steel pins.
Computer controlled key cutting combinations.
You can change your lock's combination 3 times with NO tools or Locksmith needed.

This is an ideal system for businesses where employee turnover is high.

To change combinations, simply insert a key of a different color which automatically re-sets the cylinder. The old key and combination are then permanently disabled.
When all 3 initial combinations have been used, a professional locksmith can re-combinate the cylinder and re-cut 3 new keys for about the same price as changing locks one time!
Keys cannot be made without your express consent and the presentation of the specially encrypted Owner's Card.

Highly Restrictive Key Cutting System - Your Mul-T-Lock Interactive Owner's Card is your personal pass key for ordering additional keys. Interactive is designed to discourage unauthorized key-ordering, by requiring presentation of Owner's Card at an authorized Mul-T-Lock service center.
