The lock is probably engaged. Look at the wall button, the green light is probably flashing. Hold down the lock button for 3 seconds and light should be solid. Your remotes should work now

Automatic garage door not responding to any transmitters


Sounds like you need to reprogram all the remotes. Instructions should be with the new unit and even on the back of the unit up top .I just reprogrammed all of mine. When I installed my wall unit the others quit as well so I reprogrammed them. all.

Help truck was stolen, I used remote control to "teach" truck how to open door... I reset door opener and relearned the remote..my question is do the remote have a new entry code when I learn, or remote is...


Ounce you reset ALL code of the garage door opener (engine hook up to the ceiling of the garage that open up the door), ounce you press the reset button on the unit, it disable all transmitter (portable or the one install in your vehicle). Your garage door opener has a receiver in it and your all units that you press on to open the door are the transmitter, so by pressing the reset button on the door opener, you erase all codes of all the transmitter that where programmed to open-up that door.

So if you teach your vehicle using a portable unit and you now reprogram your new vehicle with the SAME portable transmitter, then yes who ever has your stolen vehicle can come back with your stolen vehicle to your house and open up your garage door since you re-programmed the door opener using the SAME transmitter same code sent to the unite to active it).

Buy a new transmitter to re-programmed your new vehicle

Why Can't I add another remote to a merlin mt60p


If you purchase additional transmitters, the garage door
opener must be programmed to accept the new remote
code.
Program the Receiver to Match Additional Transmitter
Codes:
Using the orange "LEARN" Button:
1. Press and hold down the transmitter button you wish to
program to the opener. The orange LED will flash to
indiciate it is receiving signal from the transmitter.
2. Press and release the "LRN" button.
3. The sourtesy LEDs will flash once.
Ensure the door is clear of obstruction, then test the
transmitter.
Using the Motion Detecting Control Panel
(optional accessory):
1. Press and hold the button on the hand-held remote that
you wish to operate your garage door (1).
2. While holding the remote button, press and hold the
LIGHT button on the Motion Detecting Control Panel (2).
3. Continue holding both buttons while you press the push
bar on the Motion Detecting Control Panel (all three
buttons are held) (3).
4. Release buttons when the opener light flashes. It has
learned the code. If the light bulb is not installed, two
clicks will be heard (4).
Now the opener will operate when the transmitter push
button is pressed. If you release the transmitter push button
before the opener light flashes, the opener has not learned
the code.
To Erase all Transmitter Codes:
To deactivate any unwanted remote, first erase all codes:
Press and hold the orange "learn" button on opener until
the learn indicator light goes out (approximately 6 seconds).
All previous codes are now erased. Reprogram each remote or keyless entry you wish to learn.

Remote transmitter stopped working, changed battery, reprogrammed opener and it works but now only at a very short distance - about 1 -2 feet. Is this a transmitter issue or the opener?


There is no way to tell if you only have the one transmitter. If you have another remote or a wireless keypad that is working normally then it is that remote.

How do i program my car to open the door? i have built into my new car. everytime i try to program it, it will not work. what am i doing wrong?


  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.

I have a Quanton (3212) garage door opener. The


Hi,

We need to reset the opener unit on the wall. Unplug the wall unit. Wait for atleast 2 min. Then plugin again. Try the remote. This could solve your problem.

If it is still not working, you need to re-program the remote control to the power head.
Use the following steps:
Press the "PROGRAM" button on the garage door motor head unit once. A light "PROGRAM STATUS" will tell you that you have done so. The light will be on for around a min. In this time press the button on your remote. The light will turn off. Try opening the door with the remote now. Repeat if required. If this does not work, you will need to contact the dealer.

Cannot re-program remote transmitters for garage door opener


If both remotes quit at or about the same time then it is most likely the receiver that has quit. Especially if you have had electrical storms in the area. The receiver is part of your logic board.
