First try changing the battery in thh keypad 9V. if that dos not work just moving the wire coming from your opener towards your keypad. DONT CUT THE WIRE OR ADD TO IT. That should take care of it

My lift master security plus keyless entry pad for the garage door no longer will open the garage door when I key in the four digit code. Can I reprogram the entry pad and if sohow?thank you


You can try programming it but first make sure the battery is good. Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in any 4 digit code you like and press enter.

The remotes and keypad use the receiver which is part of the logic board.'t The button on the wall is hardwired and doesn't use the receiver. You might pull the logic board and check for bad connections on the printed circuit.
