Look in the trunk on the hinges. There should be numbers there. Answer 2: According to my owners manual for the same vehicle... 1. On the wallet card that came with the owers manual. 2. Tapped on the computer module. 3. At your dealer.
You will find a sticker in the trunck with the factory code printed on it.
The Marquis does not have a standard code. A dealer may be able to supply the factory code for the exact car, unless the code was owner changed.
Just a long shot, but check inside the trunk for a sticker.
Factory places it on the Lift Rod in the trunk. Some owners write it in the owner's manual. If the sticker is not there, you'll need to go to a dealership to get the master code.
