Hoping one of you garage door guru's out there can help. I have a Craftstman 1/2 HP garage door opener that is somewhere between 3-5 years old, I'm guessing. I inherited it when I bought the house I'm in. It came with two remotes, two keychain remotes, and has a keyless entry. Up until about a month ago, the keyless entry worked fine (the old owners gave me the code for it). Suddenly, it quit working and I have no idea why. I replaced the battery that goes in the unit, but that resolved nothing. The keypad lights up when I press the buttons, but it just won't activate the garage door when I punch in my code. I tried to call Craftsman/Sears support, since I don't have a manual for this thing, and they were no help at all. The lady I spoke with was absolutely obsessed with the question "Is it in the catalog?" and had no idea what I was talking about when I mentioned the term "keyless entry". I even asked to speak with a garage door opener product specialist but she would only tell me that if it wasn't in the catalog, they wouldn't know anything about it. Grrrf! Sears' website has equally useless information, though I've emailed their support folks as well. I'm wondering if there's any way to reset the keyless entry code or troubleshoot this problem any further. Any ideas would be greatly appreciated.
Thanks in advance,
