The Genie 40629A.S Wire Harness for Door Lock is a genuine OEM replacement part designed to connect a compatible Genie garage door opener’s control board to an external Genie door lock accessory. It restores or enables the lock function by providing the correct connector style and pinout expected by the opener, ensuring reliable communication between the operator and the lock. Ideal for replacing a damaged or missing harness, this part helps maintain secure door locking on systems that support an add-on deadbolt/solenoid-style lock.
Use the 40629A.S by routing it from the opener head to the door lock accessory and plugging the keyed connectors into the designated lock port or terminals on the operator and the lock pigtail, as directed in the owner’s manual for your specific model. This harness is intended for select Genie operators that offer a dedicated lock connection; verify compatibility in your opener’s parts list or service documentation. For safe installation, disconnect power to the opener, keep low-voltage wiring separate from high-voltage runs, and secure the harness to prevent interference with moving parts. This genuine Genie replacement helps ensure proper lock engagement for residential and light-duty commercial applications where the opener supports a wired lock accessory.
