I will be moving into a home that was a foreclosure and there are no remote openers that came with the house, but a WIRED keypad is mounted on the outside. Can anyone give me the instuctions to reset the keypad code so the previous owner cannot open the garage door?

When we bought the house 4 yrs ago, the previous owners gave us 4 different codes (she couldn't remember the code) for our Craftsman wall mounted keyless entry garage door opener which is mounted outside the garage door. None of the codes she gave us ever worked, so we never bothered with it. Now...

I mistakenly gave someone my garage door opener that didn't return it. I had a male friend come over and "change the code" including my car opener and gave me a universial which he also programmed. I came to realize my code for my keyless pad outside doesn't work (since he changed the code... )....

I have somehow scrambled my keyless entry garage entry code. How do I reset it?

How do I reset the keyless entry password on my garage door opener? It's a craftsman 1/3hp, model # 139.23325SRT.
