Absolutely doable. I always go the hard-wire approach, but this mode will also accommodate a wireless unit available here:

I am locked out of garage. Liftmaster 1265 will not open.


Sounds like what you need acces too is inside the garage. If you don't have a pedestrian access door to your garage, or a window, or these are both locked, you are going to have to break something. Sorry to tell you that. Just pick the thing to break which is easiest to repair. Once inside, there is a mechanical release (usually a pull rope hanging from the opener main unit) that allows you to open the door manually. Then you can use the garage until you can address the problem. Good luck.

My garage door opener (liftmaster 1265) buzzes when attempting to open or close the door but the chain doesn't move


Remove the cover from the motor unit and check the drive gear. It is white nylon and is just in front of the motor. Most likely stripped.

On the side of the motor unit you will find the 'down limit control'. Using a small screwdriver turn this control in the same direction as the arrow printed on the cover. Some tweaking may be necessary to get it just right.

Replace liftmaster 1245R drive/worm gear


I have a 1265 and took the cover off (unplug first).
There are screws securing the cover: 2 on each side at top, 2 at either end bottom.
Then I disconnected the chain.
There are 3 hex head screws securing the drive gear assembly (of course they thread from the inside out which makes taking them out a bit time consuming). Take care not to damage the circuit board or other electronic connections.
Then at the bottom of the shaft is the "limit switch assembly" that is clipped into the metal housing. Squeeze the 2 on the outside and it should swing free.
Then at the very end of the shaft there is another plastic gear. It is secured by a 3 prong plastic clip. Pull the outside clips away from the shaft while pushing the center piece back through the shaft. The gear should come off and you can now remove the gear and sprocket assembly up through the assembly.
call 800 528 2817 and order the "Gear and Sprocket Assembly".
I am waiting for the part and assume we reverse the order above to reinstall.
