Garage door remote won't open the garage door

Worked fine until today! When I press the remote button in my car the green light goes on ( on the remote and on the opener in the garage ) but nothing else happens. The wired opener button on garage wall works just fine .

    Our remotes just stopped working along with the keyless entry system. We're tried changing batteries and re-programming, and also checked to make sure the vacation lockout feature was not on, and nothing works. A neighbor suggested that a neighbor's new router might be causing the problem. ???

    Same problem here. Has worked fine for 5 years and now both remotes do not work but the wall button does. The lock out is off! When I push the remote the LED light on the openner flashes 3 times so it gets something.

    I have the same problem with the remote but mine is a Wayne Dalton......I can't find a button with a "padlock" on the wall.

    Seems I have the same problem with the garage door remote not working. Plus my neighbour next door has the same problem.. Happened on the same day. Though I think it is our wireless router that is causing the problem. On the day it happened, the night before we replace our anenna on our router.

    We have changed the channel on our router to see if it fixes the problem. Haven't tried it, but I'm hoping it works..

    My neighbor must have hit the lockout button after I left for work and left my door open. Now I can't get in and there is no other door. The manual key release also will not work Is there any solution now/ griccobo@msn.com

    After changed out batteries, neither remote works. The wired station works fine.

The little button with a padlock on the wall control is a "vacation" lockout feature that disables the remotes. There should be a small LED on the wall control that is always on steady. When the padlock button is pressed and released the LED should be constantly blinking (indicating the vacation lockout mode is active) and your remotes should be disabled. The wall control will still operate the door. Pushing the padlock button again should make the LED stop blinking and restore the door to normal operation.

My solution for this problem was to reset the remotes. I have a 2004 Sears opener. To reset the remotes, a reset button on the motor itself (my model's reset button is located underneath the light cover, which swings down for access, and is the same button used to reset the code), is pushed and then the remote button is held until the lights on the motor blink (in my case it took ~2 seconds).

Check out George B's solution. It worked for me, and saved me a lot of useless trouble! The little 'lock' button on the wired connection. Should turn off the blinking LED light that indicates remotes won't work...for vacation safety.

The internet has all sorts of features, some not so good, most really great.  Count this among the latter.  I'm not good at keeping track of a bunch of owners manuals, so I would have let this green light blinking phenomenon/no remote from car problem go for a long time.  One google search away, and some helpful person has solved my "problem" almost quicker than it took to search for the answer! Thanks for helping with a solution.  That's building community.  Good karma!  Thanks so much.

Coincidentally, as soon as the neighbor with the new router moved, the garage door openers started working again. Just before the problem started, geek squad was working on their router. Apparently, they changed a channel that affected all of our garage door openers (within 4-5 houses each way).

If the LED is flashing rapidly when the button on the remote is not pressed you have interference from something. Check for old remotes stored in a drawer somewhere or some new electric item nearby. Start unplugging things until that rapid flashing stops.

I have the Liftmaster Chamberlain Professional Formula I model 102.1499A and for some reason, the learn button will not sync with the homelink on two of my cars. Is there a way to reset the learn button? ...


Here is the information I have for homelink.

  1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxilary, and/or the car door must be shut).

  2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.

3. Go to the Learn Button on your garage door opener. The button is usually next to the area where the floppy antenna is connected to the motor head. With Genie it is most often behind the light lens, and an indicator light flashes red when pressed. With Sears or Liftmaster (Chamberlain) it is near, or part of, the terminal screw board, and is a red, green or purple square button with a green, amber or purple indicator light. Press this learn button momentarily. The indicator light will turn on and blink if Genie or otherwise stay lit. For Genie systems, go back to the in-car transmitter button you programmed and press this button 3 or 4 times, or until the door starts moving. This should set your in-car transmitter to your garage door opener. For Liftmaster, Sears, or Linear Megacode press and hold the in-car button you programmed until the garage opener light flashes. Your in-car is now programmed to operate your door.

How do you clear and re-enter a new code for wall mounted remote


To change the code you need to locate the smart/learn button which is near where all those white wires go. Press and immediately release it and then walk over to your keypad and key in any 4 digit code you like and press enter.

See if this works for your car.

  1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxillary, and/or the car door must be shut).
  2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done.

Pressing remotes the door won't go u[


It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

The remote opener reset button goes off and will not work


The green button is not a reset it is the program button.

If you hold the button down for about 20 seconds it will erase all codes. Then, press and release the button - press and hold the button on your remote for about 10 seconds. the next time you press it it should activate the door. Repeat the 2nd step for all additional remotes.

The lock button on the wall control locks out all radio signals for vacations etc.

If the lock has been activated the green led in the wall control will flash - when the lock is deactivated the led stays solid green.

Hope this helps
