I have a double car garage but one of the garage doors won't work with the remote, on top of that the outside keypad won't work for that door either (it works for the other one fine, and did work previously, but now doesn't recognize the password). So two problems, i need to get the password working so i can manually enter on the outside keypad to open the door, and secondly i need to get my remote working for that door. The other door and remote work fine, i have changed the baterry on the outside keypad also, and it lights up. i also changed the battery on the remote. The previous owners said they never used them, it's a 2001 home.
