Get The Strongest Lock, Get Control of Your Keys
High security locks, such as the MUL-T-LOCK, are patented keyways. They are issued to specific locksmith or security copies. That is, only the company that provided you the keys can make copies of them because no one else in the region has access to the same key blank. High security keys are the best way to establish key control.
High security keyways are patent protected. This means that there is only one manufacture that can make the key. The manufacture then issues the specific key to a security or locksmith company. As an example, ACME Locksmith owns a Mul-T-Lock keyway. We are the only locksmith in the Phoenix region with this specific keyway and are the only locksmith that can make you a key. When keys are not patent protected any company can manufacture the key, any company can buy it, and any company will copy it.
High security locks are made of the strongest material. Locks are heavier, screws are thicker, and they often contain other anti-theft measures. They are also bump proof locks. That is, there exist no key that can be used to bump the lock. Watch our video on lock bumping. When you give keys to employee, tenants, or homeowners in a HOA, copy protection is a very real concern. In all of these situations, you don’t want keys made without your knowledge. There are two primary methods to prevent key copies from being made without your knowledge: stamping keys as “DND” (Do-Not-Duplicate) and using restricted keyways.
