Lock Types

This page is designed to determine the type of lock that you need installed or repaired.


If you are interested in matching existing locks at your home or business so they are keyed alike, we must determine the type of lock you want us to match. If you do not know, look at the edge of your door where the door latch or deadbolt is. The name of the lock manufacturer is usually stamped as shown below.

This also helps us determine the brand of lock that you may need repaired.

Deadbolts (Double Cylinder)
A double cylinder with a 1" bolt is intended to reduce the potential for kicking in a door jamb or "jimmying" a lock from the outside. This lock has a key on both sides of the lock. These double cylinder deadbolts are used when there is a window adjacent to the actual door. These deadbolts prevent individuals on the outside from breaking the glass and opening the door.
