Programming Universal Home
Remote — Fixed Code
If you have questions or need help programming the
Universal Home Remote System, call 1-866-572-2728 or
go to www.learcar2u.com.
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.
Your hand held transmitter may have between eight
to 12 dip switches depending on the brand of
transmitter.
