Its located on the passenger side before the rear axle in the middle of the rear doors
If I understand your question correctly, your vehicle may have a separate relay for each function. The relay for locking the doors by using the switch has gone bad.
By using the proper code - like 12321 or whatever your code is. You put the code in and then press 1-2 to open doors 3-4 to open back doors and 5-6 to open the trunk. When exiting you press 7-8 and 9-0 together to lock everything.
5x7 / 6x8 in the doors and 6x9 in the rear deck. See more info at the links below... http://www.autoclinix.com/Mercury/Front%20Speakers.html http://www.autoclinix.com/Mercury/Rear%20Speakers.html
There could be many reasons why the 1993 Grand Marquis make noises when the doors lock. The wiring could be off, or the motor could be going out.
If you can not unlock them with a key, you will have to call a locksmith.
Have you replaced the battery in the fob?
5x7 in the front doors; 6x9 in the rear deck (or 5 1/2" mounted in 6x9 adapters). See detailed info here... http://www.autoclinix.com/Mercury/Rear%20Speakers.html
Yes, IMMEDIATELY within 3 seconds after punching in your code, hit the 5 on your pad and your trunk will pop open. also if you immediately hit the 4 the other three doors will unlock.
If the key will not work in the door or the liftgate, you will need to call a locksmith or break a window.
There is a sensor in each door. You will have to find out which door sensor is defective. Check with your local dealer for the part, and he will be able to help you.

On my 1995 Mercury Grand Marquis, you must have all the transmitters intended for use on your vehicle. Prior programing is erased and ALL must be done at the same time. 1) Enter the factory keyless entry code., 2) Press the 1/2 button on the keyless entry pad. 3) Press one button on each of the transmitters to be programmed. Each transmitter button must be pressed within seven seconds of the prior one. Each time a transmitter is successfully programmed, all of the vehicle doors will lock and then unlock to verify programming. If they did not lock/unlock, your transmitter was not programmed.
Crutchfield.com states that you can use up to 6"x8" in front doors and the same for rear deck.
The lock and unlock switch for the doors unlocks the trunk too.Push the switch to the left and hold it.
Use the remote door lock to lock the doors, then unlock, then lock. The alarm should be reset. If not get in the vehicle, lock all the doors with them closed, unlock them, relock them walla alarm reset!
I think you have to push the 'unlock' button twice in order to unlock the doors.
You have to unlock the car doors for the filler cap door to unlock. This means ALL of the doors, not just the drivers.
You have a bad sensor in one of the doors, all 4 will have to be checked. Check at you local dealer for the part. In the meantime, just pull all the bulbs out so as not to drain the battery.
It should unlock along with the doors It should unlock along with the doors It should unlock along with the doors IDK who this person is "it should unlock along with the door" whom ever posted this question I know your frustrated, me too. I have a SLk 230 1999 I have to manually unlock the doors and the truck My baby is on sit because I cant put gas in it... the doors are unlocked, the doors are unlocked
You have to press the unlock button 2 or 3 times to get both doors to unlock no programming needed
You beat the TRAINERS first then the doors unlock and you can go through them ^^
Use the key to unlock the driver side door. This will reset the alarm and the starter cutoff. i took the modul that chimes for doors out and mine stop the alarm.
click the unlock button twice. if this doesn't work contact your dealer...
