LiftMaster 041A6102 Power Door Lock Kit

Replacement Lock for Wall-Mount Jackshaft Garage Door Openers

The LiftMaster 041A6102 Power Door Lock Kit is a genuine replacement lock assembly for compatible LiftMaster and Chamberlain wall-mount residential jackshaft and RJO garage door openers. It is used to replace a failed, damaged, or missing power door lock on opener systems designed to automatically secure the garage door after closing.

A working power door lock is an important part of garage access security, especially on wall-mount opener systems where the locking function helps keep the door secured when the opener is not actively moving the door. If the original lock no longer engages, releases, or communicates properly with the opener, replacing it with the correct 041A6102 kit helps restore the intended locking function.

The 041A6102 is also known as 41A6102. Common compatibility references include LiftMaster 3800, 3800P, 3800PLD, 8500, 8500C, RJO20, and RJO20C models, depending on the opener version and parts diagram. Compatibility should be matched by opener model number and replacement parts diagram because wall-mount opener lock assemblies are not universal.

This kit includes the power door lock, installation screws, and mounting template. It is a replacement lock kit only and does not include the garage door opener, wall control, safety sensors, battery, cable tension monitor, or other opener accessories.
