If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described. The HomeLink
Transmitter may not work with older garage door
openers that do not meet current Federal Consumer
Safety Standards. If you cannot program the transmitter
after repeated attempts, refer to "Rolling Code
Programming" later in this section or contact the
HomeLink Transmitter manufacturer at

Be sure to keep the original hand
in case you need to erase and reprogram the
HomeLink Transmitter.
Canadian Owners: During programming, the
-
hand held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
-
should press and re press the button on the hand
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.

Operating the HomeLink Transmitter
Press and release the appropriate button on the
HomeLink Transmitter. The indicator light comes on
while the signal is being transmitted.
The HomeLink Transmitter is disabled when the
VALET lockout button inside the glove box is activated.
For more information, see "Valet Lockout Button" in
the Index.

If the hand held transmitter appears to program the
HomeLink Transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a "rolling
code" system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.
To determine if you have this system, press the button
on the HomeLink Transmitter that you have
programmed already. If the indicator light on the
HomeLink Transmitter flashes rapidly for two seconds
and then turns solid, the garage door opener has a
rolling code system. In a rolling code system, the
garage door motor head unit must be trained to the
HomeLink Transmitter.
