How To Delete Garage Door Code On Mercury Grand Marquie

1. CAUTION:
During this procedure, the system that you are programming will be made to
operate. Make sure that people or objects are clear of the garage door or gate
being programmed.

Verify the hand-held transmitter is operative.

2. Prepare for programming the universal transmitter by erasing all three
channels by holding down the two outside buttons until the red light begins to
flash (20-30 seconds). Release both buttons.

3. Select one of the three universal transmitter channels to be programmed by
pressing the desired button.

4. Hold the end of the hand-held transmitter 25-51mm (1-2 in) from the front
surface of the universal transmitter so that the red light can still be seen.

5. Note:
During programming, the hand-held transmitter may automatically stop
transmitting after two seconds, which may not be long enough to program the
universal transmitter. If programming this type of hand-held transmitter,
continue to hold the button on the universal transmitter while re-pressing the
hand-held transmitter button every two seconds (Canada only).

Use both hands to press the hand-held transmitter button and the desired
button on the universal transmitter. Do not release either button.

6. Hold down both buttons until the red light on the universal transmitter
flashes, first slowly and then rapidly. Release both buttons when the rapid
flashing begins. The universal transmitter has successfully learned the new
frequency signal and can be used in place of the hand-held transmitter(s).

7. Note:
If the hand-held transmitter appears to program the universal transmitter but
does not open the garage door, the garage door opener may have a "code
protected" or "rolling code" feature.

To operate, simply press the appropriate button on the universal transmitter.
The red light is on while the signal is being transmitted.
