Check your other post.

what other post? i think i've only posted this one issue. pls elaborate.

Good question. I can't find it now either but I did ask you a question and I will again. Is your keypad hardwired?

yes..keypad is hardwired to another transmitter which also operates the garage door and is located just inside of garage door.

Okay we can do it now. Follow these instructions.

First unplug the garage door opener from the electrical outlet. Next remove the nameplate from the console that the keypad plugs into and locate the program/operate switch. Flip the switch to program. Next enter your desired four-digit PIN number into the keypad. Slide the switch back to operate and plug the garage door opener back in. The keypad should be programmed.

Success! and this didn't cost me a penny and the landfill site must be happy too!

thanks Don.
