GDO w/non-functioning Openers
I have a 1/3 hp Craftsman GDO with 2 remotes that do not work, they appear to be replacement Craftsman remotes. I just moved into the home and it came with the 2 replacement remotes and a keyless entry keypad. I don't know the security code for the keypad either.
1/3 hp Craftsman
3 Button Remotes: 139.53681B
Keyless entry keypad: 139.53684
Any help how to program the remotes & keypad would be greatly appreciated.
