Rolling Code Devices
To determine if your device has a rolling code, a
good indicator is its manufacturing date.
Typically, devices manufactured after 1995
have rolling codes. A device with a rolling code
will also have a “LEARN” or “TRAIN” button
located where the antenna is attached to the
device. The button may not be immediately
visible when looking at the device. The name
and color of the button may vary slightly by
manufacturer.
NOTE:
The “LEARN” or “TRAIN” button is not the button
you normally use to operate the device.
Non-rolling Code Devices
Most devices manufactured before 1995 will
not have a rolling code. These devices will also
not have a “LEARN” or “TRAIN” button.PROGRAMMING HOMELINK® TO A
G
ARAGE DOOR OPENER
To program any of the HomeLink® buttons to
activate your garage door opener motor, follow
the steps below:
NOTE:
All HomeLink® buttons are programmed using
this procedure. You do not need to erase all
channels when programming additional
buttons.

1. Place the ignition switch into the ON/RUN
position.

2. Place the garage door opener transmitter 1 to 3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program,
while keeping the HomeLink® indicator
light in view.
3. Push and hold the HomeLink® button you want to program while you push and hold
the garage door opener transmitter button
you are trying to replicate.
4. Continue to hold both buttons and observe the
