I want to program garage door opener to my automobile Homelink system...lexus where is the so called training button on the garage door opener so I can program it to my Homelink system in car.

The control is made by HomeLink. You can find instructions on how to program your specific type of garage door here:

http://www.homelink.com/program

Here are the basic steps for a "Genie" garage door opener:

1. For first time training, press and hold the two outer HomeLink buttons, releasing only when the HomeLink indicator light begins to flash, which may take up to 20 seconds. (Do not perform this step when training the additional HomeLink buttons.)
2. Press the appropriate HomeLink button I, II or III which you want to train and keep holding it until the indicator light starts flashing slowly. Once the indicator light starts flashing slowly, you may release the button. HomeLink is now in "training mode."You will now have 5 minutes to train your hand-held transmitter to the HomeLink transmitter in the bumper.
3. Stand in front of your vehicle with the original hand-held transmitter for the garage door opener (or other device) that you wish to train.The transmitter unit to be trained is located in the bumper about 4 inches to the left of the vehicle's center.
4. Hold the original hand-held transmitter between 0-12 inches from your car's bumper. NOTE: The distance between the hand-held transmitter and the HomeLink transmitter unit in the bumper depends on the system being trained. It may require several attempts at different distances in order to pick up the signal.
5. Now press and hold the button on your original garage door transmitter while keeping your fog lights in view. The fog lights will blink three times to indicate that the training has been successful.NOTE: If the training time exceeds the five minutes, the fog lights blink once. If this happens, you should repeat steps 2 to 5.
6. Press and hold the trained HomeLink button and observe the indicator light.
   • If the indicator light is solid/continuous, training is complete and your device should activate when the HomeLink button is pressed and released.
   • If the indicator light blinks rapidly for 2 seconds and then turns a solid/continuous light, proceed with Steps 7-9 for a rolling code device. A second person may make the following steps easier. Please use a ladder or other device; do not stand on your vehicle to perform the next steps.
7. At the receiver (motorhead unit) in the garage, locate the "learn" or "smart" button (usually near where the hanging antenna wire is attached to the unit). If there is difficulty locating the training button, reference the garage door opener's manual.
8. Press and release the "learn" or "smart" button (the name and color of the button may vary by manufacturer). NOTE: Once the button is pressed, you have approximately 30 seconds to initiate the next step.
9. Return to the vehicle and firmly press and hold the trained HomeLink button for two seconds and release. Repeat the "press/hold/release" sequence up to 3 times to complete the training process.

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.

1. In the vehicle press and hold the two outside buttons until the indicator light begins to flash (after 20 seconds). Release both buttons. Note: Some vehicles may require the ignition switch to be turned to the second (or "accessory") position during the programming process.

2. Hold the end of your handheld transmitter between 1 and 3 inches away from the Homelink surface (located on your visor or overhead console) keeping the indicator light in view.

3. Using both hands, simultaneously push the handheld transmitter button and the desired HomeLink button. DO NOT release the buttons until step 4 has been completed.

4. Hold down both buttons until the indicator light on the HomeLink Wireless Control System flashes, first slowly then rapidly. When the indicator light flashes rapidly, both buttons may be released. (The rapidly flashing light indicates successful programming of the new frequency signal.)

To train your garage door opener.

1. Locate the smart/learn button on the garage door opener motor head unit.

2. Press and immediately release the smart/learn button.

Firmly press and release the programmed HomeLink button. Press and release the HomeLink button a second time to complete the training process. (Some garage door openers may require you to do this procedure a third time to complete the training.)

If you just received your vehicle and have not trained any of the buttons in HomeLink before, you should erase any previously learned codes before training the first button. To do this, press and hold the two
outside buttons on the HomeLink Transceiver for about 20 seconds, or
until the red indicator flashes.
Release the buttons, then go to step 1.
If you are training the second or third buttons, go directly to step 1.

1. Unplug the garage door opener motor from the electrical outlet.
2. Hold the end of the garage door opener remote 2 to 5 inches from HomeLink. Make sure you are not blocking your view of the red indicator in HomeLink.
3. Press and hold the remote transmitter button and one of the HomeLink buttons at the same time.
If the red indicator in HomeLink begins to flash slowly at first, then rapidly, release both buttons, and go to step 5. If the red indictor in HomeLink continues to flash slowly (does not flash rapidly), your remote transmitter may stop transmitting after a short time. Go to step 4.
4. Press and hold the remote transmitter button and one of the HomeLink buttons at the same
time. While continuing to hold the HomeLink button, press and release the remote transmitter button every 2 seconds. If the red indicator in HomeLink begins to flash slowly at first, then rapidly, release both buttons, and go to step 5. If the red indicator in HomeLink continues to flash slowly (does not begin to flash rapidly), repeat steps 2 thru 4.
5. Plug in the garage door opener motor, then test the HomeLink button by pushing it for about 1
second. If the button works, programming is complete. If the button does not work go to step 6.
6. Push and hold the HomeLink button for a few seconds, then watch the red indicator on HomeLink.
If the indicator stays on or flashes slowly, repeat steps 2 thru 5. If the indicator flashes rapidly
for 2 seconds then stays on, you have a rolling code transmitter. Go “Training with a Rolling Code System”
7. two HomeLink buttons to operate any other compatible remotely controlled devices around your
home (lighting, automatic gate, security system, etc.).
Repeat these steps to train the other

PROCEDURE:
1. For first time training, press and hold the two outer HomeLink buttons, releasing
only when the HomeLink indicator light begins to flash after 20 seconds.
NOTE: Do not perform this step when training the additional HomeLink buttons.
2. Position the hand-held transmitter 1-3 inches away from the HomeLink mirror,
keeping the HomeLink indicator light in view.
3. Using both hands, simultaneously press and hold both the desired HomeLink button
and the hand held transmitter button.
DO NOT release until the HomeLink indicator light flashes slowly and then rapidly.
When the indicator light flashes rapidly, both buttons may be released. The rapid
flashing indicates successful training and the procedure is complete. This also
indicates that the garage door opener does not use rolling code technology.
Note: The garage door may open or close during this step.
Steps 4 through 7 are only necessary if the HomeLink button appears to be
transmitting after step 3, but the garage door does not operate.
4. Press and hold the trained HomeLink button and observe the indicator light.
If the indicator light is solid/continuous, training is complete and your device should
activate when the HomeLink button is pressed and released.
If the indicator light blinks rapidly for 2 seconds and then turns a solid/continuous light,
proceed with the following training instructions for a rolling code device. A second
person may make the following steps quicker and easier. It is recommended that a
ladder or similar device be used to obtain access to the motor housing. Do not stand
on the vehicle to perform the next steps.
5. At the garage door opener receiver (motor housing) in the garage, locate the “learn”
or “smart” button (usually near the hanging antenna wire attached to the unit). If
there is difficulty locating the training button, refer to the garage door opener’s
manual.
6. Press and release the “learn” or “smart” button (the name and color of the button
may vary by manufacturer).
NOTE: Once the button is pressed, there are 30 seconds in which to initiate the
next step.

7. Return to the vehicle and firmly press and hold the trained HomeLink button for two
seconds and release. Repeat the “press/hold/release” sequence up to 3 times to
complete the training process. If successful, your garage door should open or close
during this step.
If the vehicle owner continues to have difficulty programming their HomeLink mirror,
please have them contact HomeLink customer service directly at 1-800-355-3515 or
www.homelink.com for further assistance.
PROCEDURE COMPLETE

Good luck!

called their 800 number and they walked us through re-training the opener and getting the homelink to work in both vehicles

www.homelink.com.

Try this site. There is too much information to put down here.

There are 3 programmable Homelink buttons you can use for different remotes. Just to the right of the buttons there is an indicator light.

Decide which button you want to program. Point the none battery end of your remote 1"-3" away from the Homelink panel and press both the remote and desired Homelink button down and hold them down at the same time. After about 20 seconds, the Homelink indicator light will change from a slow flashing to a rapid flashing. You can then release both buttons,
If the garage door responds to the Homelink, your done! If not, your garage door uses a rolling codes transmitter and must be trained.
Find the training button on your garage door opener's transmitter (usually mounted on the ceiling). Press the training button and within 30 seconds press and release the programmed Homelink button twice. If the garage door opener operates, you're done! If not, press and release the Homelink button a third time and the garage door should respond. If it still does not, you may have a very old garage door opener with a none digital transmitter (like I did). In that case, you either need to buy a new opener or try to replace the transmitter with a modern digital unit (as I did). Advantage: cheaper than a whole new garage door opener.
Disadvantage: The newer openers incorporate safety features that my old opener does not have.

1. Position vehicle within 10 feet of garage door- engine off and battery on.

2. Press/hold 2 outside buttons of Homelink transceiver until red indicator starts flashing rapidly, then release button. This should take about 20 seconds. This erases any previously learned codes.

3. Press/hold remote control and press/hold button of Homelink transceiver simultaneously. Slowly move remote control from 5" away to 1" away from Homelink transceiver. Release both buttons after red indicator starts blinking rapidly. This should take about 5 seconds. I discovered that the Homelink in my TL is a bit faulty because it took much longer to accomplish this than when programming the Homelink in my MDX. My TL's Homelink may "unlearn" it's code in the future and the needed proximity of the TL to the garage door may be much closer than desired until I get the Homelink fixed.

4. Press training button on garage door opener unit until the indicator lights illuminates- this should be immediate.

5. Within 30 seconds press/hold the Homelink button for 2-3 seconds until the red indicator starts flashing rapidly. Repeat a second time. It should now be programmed. Check it by pressing the programmed button on the Homelink receiver.

6. When programming more than 1 garage door opener unit, disconnect power from unit before programming more units. By not doing this the programmed unit could conflict with the unprogrammed units commands.

Problems:

1. The Battery in the garage door remote may be too weak to program Homelink. However, the battery may be strong enough to operate the garage door. One of my remote controls had a weak battery- my system was installed today, fresh out of the box. I had to use the second remote control for the programming of Homelink on my 2 vehicles.

2. Antenna on the garage door opener unit must be hanging down, fully extended.
