Installation
STEP 15 Install the Automatic Garage Door Lock
For use on Residential Garages with an Entry Door Only. Install On Sectional Doors with Torsion
Assemblies Only. Up to two locks can be installed per compatible garage door opener.
To prevent possible SERIOUS INJURY or DEATH from a closing gate or door:
l Automatic Garage Door Lock MUST be installed per the owner’s manual.
l Be sure to DISCONNECT ALL ELECTRIC AND BATTERY POWER to the garage door opener BEFORE
installing the garage door lock.
l The door MUST be in the fully opened or closed position BEFORE installing the garage door lock.
l Be sure to DISASSEMBLE and REMOVE any manual door locks that might be currently installed.
UNPLUG THE GARAGE DOOR OPENER AND DISCONNECT THE BATTERY (IF APPLICABLE) BEFORE
PROCEEDING. REMOVE ANY MANUAL LOCKS FROM THE GARAGE DOOR.
1. Attach template (provided) to track. TIP: The second roller from the bottom is ideal for most installations.
2. Drill holes as marked on template. Use a 3/4" step drill bit to drill holes as marked on the template.
OR
If not using a step drill bit, pre-drill with a smaller drill bit to assure proper placement of the 3/4" hole.
3. Fasten automatic garage door lock to the outside of the garage door track with the 1/4"-20x1/2" screws.
4. Run wire (provided) from automatic garage door lock to garage door opener. Use insulated staples (not
provided) to secure wire in several places. NOTE: If you are going to cut the wire you will need to
reconnect wire using a wire nut. Do not tape the ends together. The lock is polarized and requires you
reconnect black to black and white to white wires.
5. Plug the connector into one of the lock terminals on the garage door opener. NOTE: To install a second
automatic garage door lock, repeat installation steps on the opposite side of the garage door.
