Garage Door Locks

There are 3 types of garage door locks found on a garage door; inside lock, lock bar, and autolatch.

An inside lock is the most common kind of garage door lock. The inside lock is square and has a latch that pushes through the garage door track, and you can only lock it from the inside of the garge door. The inside lock is the most secure way to lock your garage door.

A lock bar is an outside lock that has bars on the inside of the garage door that goes through the track. This kind of lock uses a key on the outside of the garage door and was most commonly used in the 70's and 80's. This lock has an outside handle that locks with a key.

An autolatch is has two flippers on the inside and there is a piece of metal mounted on the track that it goes into on both sides of the track. The autolatch uses a key from the outside to lock and unlock, this is the safest outside lock device on a garage door.

Grove City Garage Door Inc. recommends that if you are going to use a locking device to use an inside lock. If you have a Chamberlain, LiftMaster, or Linear opener you do not need a locking device. If you have a inexpensive garage door opener you will need a locking device, because we have found that the inexpensive openers may or may not lock when the door is in the down position.
