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.
