Asked by Mar 02, 2008 at 08:06 PM about the 1999 Mercury Grand Marquis

Question type: Maintenance & Repair

Owner's guide says it would be taped to the computer module.  I can't find it anywhere and am just curious what the code is.  Just in case we needed it. The original owner is pretty old now and suffers from some memory loss and couldn't remember.  Thanks.

go to a Merc dealer, prove you own the car, and they will run the VIN and get you the code.

Yes, these lock modules typically have the keycodes long gone after almost 10 years. :)

Pull 4 screws ( 1 visible on left about center, 2 behind rubber inserts on upper door pull, 1 under the switch panel after you unsnap it and lift it out) and then pull the whole panel straight up about 1 inch and then out. The code is on the module in the lower right area, and the sticker is on the lower right area of the module. The code is just above the bar codes.
