Hi all

Does anyone know howto change the code on a very old Sears garage door
opener. It is the super old style where you have to press 2 buttons on the
transmitter to open or close it. Has to be proibably 25 39 years old. The
remote only has one bar you press to activate it. Thanks. Happy summer

- The oldest ones I had used to use dip switches
- inside the remote and inside the receiver.

Same here. Mine's c. 1992-94 from Sears. Never had one minute of trouble with opener. Only have had to change batteries in the remote every few years.
