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).
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.
