Our lift-master garage door opener can only be operated with the wired control now. Both remote controls suddenly stopped working the same day. Changing the battery didn't help. I also tried reprogramming them, but the opener didn't take. It's almost like the remote controls are "locked" out. But I also tried locking and unlocking the opener with no luck.
It seems that the reciever part is defective, likely to surge or lighting, you have to have that module replaced.
