Hi we just purchased a craftsman keypad, successfully installed it and its operating fine. The problem is our car remotes don't work now. I've lost the instruction books for the 1/2 hp model. Any help? Thanks in advance.
You were most likely sold the wrong keypad. If you program your remotes so that they work you will find the keypad doesn't. Take the model number off the motor unit. It will look something like this: 139.XXXXXSRTX.
