I have a Sears Craftsman chain garage door opener. I gave up on the remotes that came with it. I had my security company program several fobs that include arming and disarming my home security system as well as my garage door. My problem is that I have a code that my family and I use and have another code that cleaning people etc use. That one quite working and I need to program in a different code. I lost the instructions that tell how to program in another code from the keyless pad. Can anyone help? My garage door was installed in 5/04 so it's an older one.
