Programming Universal Home
Remote — Fixed Code
Most garage door openers sold before 1996 are
Fixed Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these
actions, the device will time out and you will
have to repeat the procedure.
To program up to three devices:
1. To verify if you have a Fixed Code garage door
opener, remove the battery cover on your hand
held transmitter supplied by the manufacturer
of your garage door opener motor. If you see
a row of dip switches similar to the graphic
above, you have a Fixed Code garage door
opener. If you do not see a row of dip switches,
return to the previous section for Programming
Universal Home Remote – Rolling Code.
