Trying to program my homelink transmitter to the garage door on my house and my MIL's house. I've done it a couple of times, always according to the owner's manual. It seems to program to the already programmed openers we have, but doesn't seem to want to program to the actual garage door motor. Anybody had any luck with these things? Are they just too old now? Thanks! PFA
