I have an "Overhead Door, Model 656 Garage Door Opener" and I ran over the only remote I have. I bought a universal opener that turns out not to be so universal. I want to try resetting the dip switches, but I can't find them. Any suggestions? Thank you.

Look for the model # of your opener,you'll need it to get the info.

I agree with KBC, Wireless Keypad Programming you should get your remote directly from these folks and follow their instructions.
