Step 5:

When the indicator lamp 6 flashes 
rapidly, release both buttons.

Step 6:

Press and hold the just-trained inte-
grated signal transmitter button and 
observe the indicator lamp 6.

If the indicator lamp 6 stays on con-
stantly, programming is complete and 
your device should activate when the 
integrated signal transmitter button is 
pressed and released.

Step 7:

To program the remaining two buttons, 
repeat the steps above starting with 
step 3.

Rolling code programming

To train a garage door opener (or other roll-
ing code devices) with the rolling code fea-
ture, follow these instructions after 
completing the “Programming” portion 
(steps 1 through 6) of this text. (A second 
person may make the following training 
procedures quicker and easier.)

Step 8:

Locate “training” button on the garage 
door opener motor head unit.

Exact location and color of the button 
may vary by garage door opener brand. 
Depending on manufacturer, the “train-
ing” button may also be referred to as 
“learn”or “smart” button. If there is dif-
ficulty locating the transmitting button, 
refer to the garage door opener opera-
tor’s manual. 

i

The indicator lamp 6 flashes the first 
time the signal transmitter button is 
programmed. If this button has already 
been programmed, the indicator lamp 
will only start flashing after 20 sec-
onds.

i

If the indicator lamp 6 flashes rapidly 
for about two seconds and then turns 
to a constant light, continue with pro-
gramming steps 8 through 12 as your 
garage door opener may be equipped 
with the “rolling code” feature.

Step 9:

Press “training” button on the garage 
door opener motor head unit.

The “training light” is activated.

You have 30 seconds to initiate the follow-
ing step.

Step 10:

Firmly press, hold for two seconds and 
release the programmed integrated 
signal transmitter button (3, 4 
or 5).

Step 11:

Press, hold for two seconds and re-
lease same button a second time to 
complete the training process.

Some garage door openers (or other rolling 
code equipped devices) may require you to 
perform this procedure a third time to 
complete the training.

Step 12:

Confirm the garage door operation by 
pressing the programmed integrated 
signal transmitter button (3, 4 
or 5).

Step 13:

To program the remaining two buttons, 
repeat the steps above starting with 
step 3.

Gate operator/Canadian programming

Canadian radio-frequency laws require 
transmitter signals to “time-out” (or quit) 
after several seconds of transmission 
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this 
Canadian law, some U.S. gate operators 
are designed to “time-out” in the same 
manner.

If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the 
programming procedures, replace step 4 
with the following:

Step 4:

Continue to press and hold the inte-
grated signal transmitter button (3, 
4 or 5) while you press and re-press 
(“cycle”) your hand-held remote con-
trol transmitter 1 every two seconds 
until the frequency signal has been 
learned. Upon successful training, the 
indicator lamp 6 will flash slowly and 
then rapidly after several seconds.

Proceed with programming step 5 and 
step 6 to complete.

Operation of remote control

 Switch on ignition.

Select and press the appropriate inte-
grated signal transmitter button (3, 
4 or 5 to activate the remote con-
trolled device.

The integrated remote control trans-
mitter continues to send the signal as 
long as the button is pressed – up to 
20 seconds.

Erasing the remote control memory

 Switch on ignition.

Simultaneously hold down the signal 
transmitter buttons 3 and 5, for ap-
proximately 20 seconds, or until the in-
dicator lamp 6 flashes rapidly. Do not 
hold for longer than 30 seconds.

The codes of all three channels are 
erased.

Reprogramming a single integrated 
signal transmitter button

To program a device using a signal trans-
mitter button previously trained, follow 
these steps:

Press and hold the desired signal trans-
mitter button (3, 4 or 5). Do not re-
lease the button.

The indicator lamp will begin to flash af-
ter 20 seconds. Without releasing the 
integrated signal transmitter button, 
proceed with programming starting 
with step 3.

i

If you sell your vehicle, erase the codes 
of all three channels.
