HomeLink works in vehicle... unable to program hand held or remot

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.

If this is the 3 button HomeLink Transmitter usually centered overhead above the rear-view mirror, this should work:

While the engine is turned off follow these steps to program up to three channels:
1. Decide which one of the 3 channels (one of the 3 HomeLink buttons) you want to program.
2. Press & hold the desired button through step 3.
3. When the HomeLink indicator light begins to blink slowly(this may take up to 30 seconds), hold your hand-held garage door remote about 1 to 3 inches away from the buttons & then press and hold the button on your garage door remote. Continue to hold both buttons until the indicator light on the HomeLink begins to flash rapidly(this may take up to 90 seconds).

If it still doesn't work, make sure the batteries in your garage remote are not weak, and try again moving the remote back & forth and left & right or turning it upside down while programming.

Also note HomeLink will not work with older garage door openers, especially not with ones manufactured before April 1st 1982.

Detail Instructions from the owner's manual 1. Turn off engine
2. Prepare transmitter by erasing all three of the factory default channels by holding down the two outside buttons until the red light begins to flash. Release both buttons.
3. Hold the end of your hand-held transmitter (garage door remote) against the Homelink transmitter keeping the red light within the Homelink icon in view.
4. Using both hands push the hand-held transmitter button and the deisre button to be programmed on the Homelink transmitter. Do not release the buttons at this time.
5. Hold down both buttons until the red light on the universal transmitter flashes, first slowly then rapidly. When the light flashes rapidly, release both buttons.
To program the remaining two buttons, follow steps 3-5.

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

NOTE: Some vehicles may require the ignition to be turned on or to the second (or"accessory") position for programming and/or operation of HomeLink. It is also recommended that a new battery be replaced in the hand held transmitter of the device being programmed to HomeLink for quicker training and accurate transmission of the radio frequency. Please use a ladder and do not stand on your vehicle during the programming steps for a rolling code opener.

Rolling Code Programming:
1. Press and hold the two outer HomeLink buttons until the indicator light begins to flash (after 20 seconds). Do not hold for longer than 30 seconds. Do not repeat this step to program additional HomeLink buttons.

2. Place the hand-held remote 1-3 inches from the HomeLink button you want to program.

3. Simultaneously, press and hold both the HomeLink and hand-held remote buttons. Do not release either button until step 4 has been completed. (If you reside in Canada, refer to the "NOTE" below.)

4. When the indicator light changes from a slow blink to a rapid flash, release both buttons.

5. At the garage door opener receiver (motorhead unit) in the garage, locate the"learn" or "smart" button (usually near where the hanging antenna wire is attached).

6. Press and release this "learn" or "smart" button. (The name of these buttons vary by manufacturer.) There are 30 seconds in which to initiate step 7.

7. Firmly press, hold for two seconds, and release the programmed HomeLink button. Do this procedure again and, depending on the make of your garage door opener, do this procedure a third time to complete the procedure.

The garage should now activate when the programmed HomeLink button is firmly pressed and released. If not, give us a call or refer to the "Troubleshooting Tips" noted below. NOTE: If you reside in Canada, replace step three with the following: Press and hold the desired HomeLink button and "cycle" the hand-held remote. To cycle: Press and release the hand-held remote button every two seconds until the indicator light changes from a slow blink to a rapid flash(step four).

Troubleshooting Tips:

** Check the frequency of the garage door opener's hand-held remote (usually found on the back). HomeLink is compatible with radio-frequency devices operating between 288-399 Mhz.

** Put a brand new, store bought battery in the hand held remote. During the programming process (step three above) the battery's energy tends to drain (more so with an older battery). A new battery will increase the speed and accuracy in which the hand-held remote sends its signal to HomeLink.

** Retrain HomeLink holding the hand-held remote at different lengths and angles from the HomeLink button you are trying to program (during programming step three). Try 4-6 inches away at a different angle.

** Confirm that the HomeLink button you are trying to program is in the "programming mode". Press and hold the desired button. The indicator light will be a slow blink when HomeLink is in the "programming" mode and can be programmed at any time.

Verifying HomeLink has picked up a rolling code signal:

** Press and hold the programmed HomeLink button. If the indicator light blinks rapidly for two seconds and turns solid, HomeLink has successfully picked up the rolling code signal. If necessary, proceed with steps 5-7 noted above to complete the rolling code programming.

The only way to program Homelink without a garage door opener remote is if you have a keypad that allows access to your garage. I tried EVERYTHING and then realized I had the keypad which is wireless; I simply unscrewed the battery operated keypad from its location and held it 1"-3" from the Homelink buttons in my car. I then punched in my code and held the enter button on the keypad at the same time as the Homelink button I wished to program. It worked flawlessly. Good Luck!!!!

Hi my name is Allen!

Program a previously trained homelink button as follows... 1. Press and hold the desired pre-programmed HomeLink button for at least 20 seconds (but no longer than 30 seconds) until the indicator light begins to flash. Without releasing the HomeLink button, position the hand-held transmitter 1-3 inches away from the homeLink surface keeping the HomeLink indicator light in view. 2. Using both hands, simultaneously press and hold both the desired HomeLink button and hand held transmitter button (or press and "cycle" - as described in "Gate and Canadian programming"). 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 programming) The previous device has now been erased and the new device can be activated by pushing the HomeLink button that has just been programmed. however, it may be necessary to follow steps 5-7 of the "programming" section to complete the rolling code training. This procedure will not affect any other programmed HomeLink buttons.

how about a real answer......

1. Press and hold the two outer HomeLink buttons, and
release only when the indicator light begins to flash (after
20 seconds). Do not hold the buttons for longer than 30
seconds and do not repeat step one to program a second
and/or third hand-held transmitter to the remaining two
HomeLink buttons.

2. Position the end of your hand-held transmitter 1-3
inches (3-8 cm) away from the HomeLink buttons while
keeping the indicator light in view.
3. Simultaneously press and hold both the HomeLink
button that you want to train and the hand-held transmitter
buttons. Do not release the buttons until step 4
has been completed.

4. The HomeLink indicator light will flash slowly and
then rapidly after HomeLink successfully receives the
frequency signal from the hand-held transmitter. Release
both buttons after the indicator light changes from the
slow to the rapid flash.
5. Press and hold the just trained HomeLink button and
observe the indicator light. If the indicator light stays on
constantly, programming is complete and your device
should activate when the HomeLink button is pressed
and released.

The built-in system in your '98 Jeep is made by a company called "HomeLink", a subsidiary of Johnson Controls Inc. The website, www.homelink.com, has a walk through tutorial that should do the trick. It's a matter of taking and existing hand-held remote control for your opener, pressing and holding its button, and pressing and holding the button you wish to use in the visor at the same time (with the remote positioned very close to the visor). The appropriate flashes on the LED above the row of three buttons will let you know when the HomeLink system is set up. Depending on you opener, you may then need to locate a "learn" button on the overhead garage door opener mechanism, and program the HomeLink system into the opener's memory.
