Get The Strongest Lock

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.

High security locks often weigh 2X that of a standard lock. Additionally, locks like Mul-t-lock product have included technology that can secure the bolt of the lock to the frame so that they cannot be seperated.

Establish Key Control

Businesses relying on keys that are stamped as Do Not Duplicate (DND) currently have NO protection from an employee or member making as many copies of that key as they wish.

High security locks, such as the MUL-T-LOCK, are patented keyways. They are issued to specific locksmith or security companies. This means that only the company that provided you the high security key can make a copy of it. No one else in the region has access to that key blank. High security keys are the best way to establish key control.

As an example, ACME Locksmith owns a specific 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.

There are varying levels of restricted keyway protection to gain key control. Which is right for you should be discussed with your commercial locksmith service.

  • No protection. Widely available keys that can be copied in any machine at any big box store.
  • Restricted keys. Keys that are only sold to security companies, such as locksmiths. They aren’t generally available at big box stores. The benefit of these keys is that the locks they go to are generally high security so offer all of the protections of a high security lock, and you can get duplicate keys more easily (by presenting a verification card issued when you bought the high security locks), because you can go to any locksmith.
  • Patented keys. The strongest key control. Your keys can only be made by one company in your region and will only be made when someone presents the verification card.
