When To Choose Keyed Alike or Keyed Different


Keyed alike and keyed different, honestly what’s the difference? With all these lock codes and options, the simple act of purchasing a new lock can be seriously daunting. Well we’re here to shed some light on the issue of keyed alike and keyed different, and after reading this post you’ll see that their differences are actually pretty simple.

The choice between keyed alike and keyed different comes down to convenience versus security. With keyed alike you can have multiple locks or padlocks that’re all operated by a single key. This makes it easier for the  foreman or maintenance official as they won’t have to lug around a bunch of keys, not to mention they won’t have to remember what unlocks what. Keyed alike equals convenience, and is best suited for indoor applications where efficiency is favored over security.

Keyed different on the other hand is what most are accustomed to. When locks are keyed different each lock is operated by a unique key, allowing the lock to only be opened by some one who has the original key or an exact copy of it. While keyed different may be less convenient, it’s your most secure keying option. Keyed different is best used for securing your perimeter where security is paramount.

As previously stated the main difference between keyed alike and different is convenience versus security. It’s a simple concept on paper but finding the perfect balance for your facility is still a challenge. So make sure to choose keyed different for your perimeter while enjoying the convenience of keyed alike in your indoor applications.
