Universal Remote System
Programming
Vehicles with the Universal Remote
System will have these buttons
located in the headliner.
This system provides a way to
replace up to three remote control
transmitters used to activate devices such as garage door
openers, security systems, and
home automation devices.
Do not use this system with any
garage door opener that does not
have the stop and reverse feature.
This includes any garage door
opener model manufactured before
April 1, 1982.
Read the instructions completely
before attempting to program the
transmitter. Because of the steps
involved, it may be helpful to have
another person assist with
programming the transmitter.
Be sure to keep the original remote
control transmitter for use in other
vehicles, as well as for future
programming. Only the original
remote control transmitter is needed
for Fixed Code programming. The
programmed buttons should be
erased when the vehicle is sold or
the lease ends. See
“Erasing
Universal Home Remote Buttons” in
this section.
