When adding a garage door opener to your garage door, it is a good idea to remove the garage door lock. The opener acts as a lock when the door is down, therefore eliminating the need for a manual lock. Removing the old lock is a safety measure to prevent accidental locking that could damage the new opener. If you do not want a hole left in your door, you can always leave the outer lock assembly on the door.
Close the garage door fully. Do not lock it. Look for a small metal pin securing the inside T-handle to the garage door lock. Grab the tip of the pin and pull it out. If you cannot grab the pin, insert a finishing nail into the bottom of the pin hole. Tap the finishing nail with a hammer to drive the pin out of the lock. Pull the T-handle off the lock.
Pull the lock bar plate off the centre lock shaft where the T-handle was mounted. The lock bars are the long bars that stretch from the lock to the end of the door. Each lock bar attaches to the lock bar plate. Manoeuvre the ends of the lock bars out of the guides on each end of the door panel when pulling the lock bar plate off.
Remove the two screws securing the front of the lock assembly to the door with a flathead screwdriver. The screws mount from inside the door through a retaining plate and the door.
Disconnect the lock bar guides off each end of the door panel. The lock bar guides are attached to the door with two screws. Removal them with a Phillips-head screwdriver.
Go outside and pull the outer lock assembly away from the garage door.
