You cannot reprogram it. A dealer can get you the Master Code if you've lost it.
thats my question to you
1. Call a Locksmith or 2. Break the window.
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.
You just might possibly find a sticker in the trunk somewhere.
You will find a sticker in the trunck with the factory code printed on it.
Just a long shot, but check inside the trunk for a sticker.
Mine was under the trunk lid. When you open the trunk you can see it up underneath towards the back. A white sticker with 5 black numbers on it. '94 Grand Marquis
The default location is on the Trunk Riser inside of the trunk on the left or right side. Look for a sticker.

Usually on one of the Trunk Lift Rods. If you can't find it, a dealer can look up the Master Code for you.
