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

Reprogram all features of the garage door lift system.

does the wireless keyless entry have batteries

The correct keypad for your opener is 139.53684. The 53876 keypad is an older technology and will not work correctly. If you program it you will find your remotes no longer work and if you reprogram your remotes the keypad will not work.

not compatable-u will need keyless from chamberlain

Call Domino. Sounds like button on pad worn out. Confirm by trying new code with ALL FOUR numbers different. If it works, you can just change you code. If you have patience, find the bad button , ie: If code were 6529, try 6666 and see if it works. If not, 6 is 6. If yes, try 5555. You get the idea.

Yes, you purchased the wrong wireless. You must get a Genie keyless and there are two types of Genie keyless (GWKP & GWK-BL) depending on which Genie operator you have. You might think about a wired keyless entry (Domino GD-1). Then if you change your operator you don't have to change your keyless.

THE FREQUENCY OF THE UNITS ARE PROBABLY NOT COMPATABLE THEY CHANGED ABOUT 2 YEARS AGO.

SORRY - I THINK YOU NEED A NEW KEYPAD TO GO WITH THE NEW OPENER.

Press the learn code button on the back (or side) of the operator. with in @ 40 secs. press in your 4 digit code on your keyless and press the enter button @ 2 secs.

If you have a keyless entry it will still open the door with the vacation lock on. I assume you tryed this or don't have a keyless entry. There is no other way to activate the operator. Sorry but you will have to make a way in.
