6. Locate in the garage, the garage door opener

receiver (motor-head unit). Locate the “Learn”

or “Smart” button. This can usually be found where

the hanging antenna wire is attached to the

motor-head unit.

7. Firmly press and release the “Learn” or “Smart”

button. The name and color of the button may

vary by manufacturer.

You will have 30 seconds to start Step 8.

8. Return to the vehicle. Firmly press and hold the

programmed HomeLink

button for two seconds,

then release. Repeat the press/hold/release

sequence a second time, and depending on the

brand of the garage door opener (or other rolling

code device), repeat this sequence a third time

to complete the programming.

HomeLink

should now activate your rolling-code

equipped device.

To program the remaining two HomeLink

buttons,

begin with Step 2 of “Programming HomeLink

.” Do not

repeat Step 1.

Gate Operator and Canadian

Programming

Canadian radio-frequency laws require transmitter

signals to “time out” or quit after several seconds of

transmission. This may not be long enough for

HomeLink

to pick up the signal during programming.

Similarly, some U.S. gate operators are manufactured to

“time out” in the same manner.

If you live in Canada, or you are having difficulty

programming a gate operator by using the

“Programming HomeLink

” procedures (regardless of

where you live), replace Step 3 under “Programming

HomeLink

” with the following:

Continue to press and hold the HomeLink

button while

you press and release every two seconds (cycle) your

hand-held transmitter until the frequency signal has been

successfully accepted by HomeLink

. The indicator light

will ﬂash slowly at ﬁrst and then rapidly. Proceed with

Step 4 under “Programming HomeLink

” to complete.

Using HomeLink

Press and hold the appropriate HomeLink

button for at

least half of a second. The indicator light will come

on while the signal is being transmitted.
