Review title: It worked...but then all other remotes didn't
Product review: I have a Craftsman 139.536xxx garage door opener. Attempting to replace a 139.53684 SECURITY+ keyless entry pad, I purchased the 977LM Liftmaster+. I was able to program the 977LM, but all my other remotes were rendered useless during the new keypad programming process. There was no way to program the new keypad AND my car remote or OEM transmitter. With two hours invested and considering a return with a minimum $10 restocking fee and return shipping costs makes me wish I had ordered one from the OEM for twice as much.
