▼Pre-programming the HomeLink
System
NOTE
It is recommended that a new battery
be placed in the hand-held transmitter
of the device being programmed to
HomeLink for quic
ker training and
accurate transmission of the
radio-frequency signal.
Verify that there is a remote control
transmitter available for the device
you would like to program.
▼ Programming the HomeLink
System
The HomeLink system provides 3
buttons which can be individually
selected and programmed using the
transmitters for current, on-market
devices as follows:
1. Press and release the HomeLink
button you would like to program.
The indicator light flashes slowly in

2. HomeLink button

2. Hold the hand-held transmitter 2.5 to 7.5 cm (1 to 3 in) away from the
HomeLink button you would like to
program while keeping the
indicator light in view.
NOTE
Depending on the hand-held
transmitter, it may be easier to do
the programming by holding it 15
to 20 cm (6 to 7.8 in) away from
the HomeLink button.
3. Press the hand-held transmitter button continuously until the
indicator light changes from amber
(flashing) to green (on/flashing).
NOTE
Some gate operators and garage
door openers may require you to
replace this Programming Step 3
with procedures noted in the “Gate
Operator/Canadian Programming”
section.
4. Press the HomeLink button again to check if the programming has been
completed.
If the indicator light remains on in
green, the programming is
complete and the device
becomes operational.
If the indicator light flashes
rapidly in green, firmly press and
hold the Homelink button and
release it after two seconds have
passed. Repeat this process up to
three times to complete the
programming. The device
becomes operational and
programming is complete. If the
device does not operate, go to
the next step.
5. At the garage door opener receiver (motor-head unit) in the garage,
locate the “learn” or “smart” button.
This can usually be found where the
hanging antenna wire is attached to
the motor-head unit.
6. Firmly press and release the “learn” or “smart” button. (The name and
color of the button may vary by
