The light in my Homelink system does not come on. Therefore it cannot be programmed.


The following are steps to programming a rolling code door opener to the Homelink transmitter in the Touareg.

The instructions in the owner's manual are correct, but after following them, my garage door installer and I discovered a few quirks and fixes for them.

It is important to park the Touareg in front of the garage door. Be careful not to park underneath it. rolleyes.gif

If your remote garage door transmitters are already programmed to your door opener, you need to do the following steps:

1. On the garage door opener itself, there is a learn button. Press and hold down the learn button until the learn indicator light goes out (approx. 6 seconds). (The learn button is near the antenna on your door opener.) By doing this, you have just reset the codes. At this point your remote door transmitters will most likely not work. This is o.k.

2. In the Touareg, press and hold whichever homelink button you want to program until the light above the homelink buttons slowly blinks. Continue to hold the button in and at the same time, hold your remote transmitter underneath the map lights and press the button. Continue to press both buttons until the homelink light rapidly flashes. Let go of both buttons.

3. You now have 30 seconds to press the learn button on your garage door opener. Press it once. The light will start to blink.

4. Go back to the Touareg, press and hold the homelink button you just programmed for 3 seconds until you get a blinking light. Repeat again. This time, it should open or close the door. The homelink button is now programmed.

5. Now that the homelink button is programmed, you now have to re-program your remote transmitters. Take the transmitters with you.

6. On the garage door opener, press the learn button, the light will blink. Now press the button on the remote transmitter. The light should stop blinking. Repeat the step if you have more than one transmitter. You should be all set. The homelink button should work in the Touareg and your remote transmitter(s) should also work.

In summary, the rolling codes in the door opener receiver have to be reset. For some reason, the Touareg has to be programmed FIRST. Then the remote transmitter units. If the remote transmitter units are already programmed, you will most likely not be able to program the homelink in the Touareg for a rolling code door opener.

I have a liftmaster Model 1240. Door will open by remote or wall opener. The door will only close while holding wall opener button down. If i try and close via remote, light starts blinking and door...


The only thing that will cause the main light to flash 10 times and the door to reverse to the open position is a sensor problem. Make sure the light on each sensor is on and not flickering ever so slightly. Make sure they are not moving when the door starts to close. Lights on sensors should not blink. One light should stay on constantly and the other sensors light should go off when you block the sensors.

Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have a bad sensor.

I have a 1/2 hp craftsman opener. Remotes work fine. Wired wall unit has a blinking light on the open button and will not work Lock pad and light pad work but not the operate pad.????


Try pressing and holding the lock button for 3 seconds to stop the light from blinking. Your wall control may be bad. Usually when that light is blinking it is the remotes that will not work.

How do you set the garage door opener for a 2004 toyota 4runner LTD?


You hold the remote close to the three buttons on the vehicle. You choose which button you want the remote to transmit to, and you hold it down. With your other hand, depress the garage door remote opener, and hold it very close to the 3-button assembly. Wait for the red L.E.D. light to blink slowly. If it does not blink slow, continue moving the remote around, until it does blink slow. When it starts to blink slowly, stop moving the remote around. Wait until the light starts blinking rapidly. When the light blinks rapidly, the process is complete.

Door will not close with remote.


The code you are seeing with 5 blinks is "RPM sensor or motor overload." We can eliminate the motor overload because the door is trying to close. The RPM sensor is a small printed circuit board just in front of the motor. It's a snap to replace and is available at any good door opener company. They will know exactly what you are talking about if you ask for an RPM sensor board.

The wall button has a green light that is blinking and the car remote will not operate the garage door but the wall button works


this just happened to us today as well. the wall pad has three buttons: one large back-lit button pad to open it and a lock button and a light button. the open button was blinking quickly and would open the door, but the car remotes did not work. I found that by pushing both the "lock" and "light" button at the same time for about 3 or 4 seconds, the back-lit "open" pad stopped blinking and went to steady green. I went back to the cars and checked the remotes there. both opened the door.

hope this helps someone out there

Door opens on it own and light blinks


  • Stuck remote control button. Check all remotes. check LED on receiver.
  • Staples around Multi-Function Control Panel bell wire could be cutting into that wire. Remove wires from opener and test. Replace staples causing intermittent short.
  • Multi-Function Control Panel could have sticking door control push bar. Remove wires from control panel and test. Replace control panel if defective.
