At the bottom of the key pad is a small rectangular slot. Using a screw driver, press in and with the other hand slide the cover down. If this solves your problem, please rate me. thanks,

That keypad should work with your opener. I suspect the keypad is bad if you have other remotes that work. If not it could be the logic board.

Open the battery compartment and remove the screw. Now using the **** of your hand, hit up on the bottom of the keypad. It needs to move up about 1/4 inch and then will come off the wall.

Just bought a new PD210DM opener but still have


I don't know this model. (in australia). the chamberlains here are probably the same. the 4 digit code you first put in the keypad is what you have to use. push the learn button on your operator then punch in your 4 digit No. Hold the enter button on your keypad until the light flashes on the operator.
That should code it in.

Keyless remote will not learn new 4 digit code


Press and immediately release the smart/learn button and walk over to the keypad and key in your 4 digit code and press enter. If this doesn't do the job your keypad is probably bad.
