Try this:

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 the keypad and key in any 4 digit code you like and press enter.


If this doesn't work it is most likely the keypad has just failed.

We have a Chamberlain Whisper Drive Plus. The keyless entry stopped working, suddenly. I have changed the battery, not the problem. I cannot get it to work, and cannot get it to reprogram. The keypad lights up when buttons are pressed, but when I press "Enter" the whole keypad flashes for about 30 seconds and then just goes dark.

Garage door opener keypad stopped working. cannot reprogram it.


It could just be you need to replace the battery.
The warning light might be a "battery low" warning - advising you to replace it!
If it stops flashing, the battery has died altogether.

Keylees entry and remote controls do not work at the same time


There are two types of technology with this operator (rolling code and non-rolling code). This operator will except one or the other but not both. It is not uncommon for a rolling code (Security+) remote or keyless to lose the "rolling"part of its technology and become a non-rolling code device so it is not compatable with the rolling code technology. You will need to replace the one remote or keyless that is not like the others.
