Factory garage door opener

I hope this helps.

Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the stop and reverse
feature. This includes any garage door opener model
manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Decide which one of the three channels (one of the
HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly (this may
take up to 90 seconds).
If you have trouble programming HomeLink, make
sure that you have followed the directions exactly as
described and that the battery in the hand-held
transmitter is not weak. If you still cannot program it,
move the hand-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
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 "Training a Garage Door Opener with
Rolling Codes" later in this section or contact the
manufacturer of HomeLink at 1-800-355-3515,
or on the internet at www.homelink.com.
Be sure to keep the original hand-held transmitter in
case you need to erase and reprogram HomeLink.


Training a Garage Door Opener with a
"Rolling Code" Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to HomeLink, see "Programming the
HomeLink Transmitter" listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the "Learn" or "Smartbutton" on the garage
door opener motor head unit. The exact location and
color will vary by garage door opener brand. If you
have difficulty finding the Learn or Smart button,
refer to your garage door opener owner's manual or
contact the manufacturer of HomeLink at
1-800-355-3515, or on the internet at
www.homelink.com.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.
2. Press the Learn or Smart button on the garage
door opener motor head unit. An indicator light will
begin to flash when the motor head unit enters the
training mode.
Following this step, you have 30 seconds to
start Step 3.
3. Return to HomeLink in your vehicle and firmly
press and release the programmed HomeLink button
three times.
The rolling-code garage door opener should now
recognize HomeLink. You may either use HomeLink
or the hand-held transmitter to open the garage door.
If after following these instructions, you still have
problems training the garage door opener, contact the
manufacturer of HomeLink at 1-800-355-3515,
or on the internet at www.homelink.com.

Depending on the type of vehicle home remote system you have and the type of garage door opener installed will determine how you program the system in your vehicle.
Below is a web address for the owners manual to your Buick. It will show you step by step how to set your Buick's remote system to open your garage door.
Good luck.

go to the link below (GM web site for owners) and then select your year and model, U will need a Yahoo mail account to sign in.

owner manual has instructions. Your garage door opener changes codes every time it is used so you need to push a button on your door motor and then run back to car to program while the door motor is willing to accept programming.

Most openers are programmed the same. You normally program the house garage opener to accept the new remote. Your garage opener will have a button to press to add in a new remote. Normally you press this and then press the remote in the car and hold until your lights on your opener flash or the garage door closes. (check your manual on your garage door opener)

you probably have a garage door opener that changes the code after each opening. I had to push a button on the door motor and then run to the car and push the opener button within 15 seconds. Your car salespwrson is usually an expert at this.

The solution is in the owners manual.If you want to program the "homelink transmitter" in your car,you will need a remote unit for your garage door opener to do this.It is fairly easy and straightforward.I programmed my 07 Pac and it works great.Good luck!

The owners manual has the procedure for the programming and the number for "homelink" customer support to help with rolling code garage door openers.
