Screw the garage door deadbolt coupling to both side rails on the sides of your garage door. Connect the long steel wires to each deadbolt connector on each side of the garage door. The wires should reach the center of your garage door. Drill a hole in the middle of your garage door at the height you mounted the side deadbolts. Fit the wedge operated door handle through the hole in the middle of the garage door with the handle on the outside of your garage door.
Screw the inside attached to the handle stem on the inside of the garage door. Connect the deadbolt wire connector to the door handle eyelets on the inside of the garage.
