Cannot get keyless entry to work. Bought new keyp...

Yes it sounds like you got the wrong keypad for your model opener.

As you may know by now there are keypads and then there are keypads. They must be made to work together as there are some that are not compatible. Posting your model numbers might help a little.

I think your keypad has just failed. Needs replacing.

If your opener doesn't have safety sensors in the doorway this keypad will not work with it.

If the following instructions don't work and you have a good battery the keypad has failed.

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 your 4 digit code and press enter.

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.

They will not work together. You need to get the keyless entry for your chamberlain garage door opener. Or got a wired system gd-1 from Domino

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

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.

You have to press a Yellow/Purple button on the back of the garage door opener unit.
It is the LEARN button. Then enter a new four digit code into the keypad and press the enter button.
The unit should click and the lights should flash. This acknowledges it has learned the new code.
