how can i find the door lock code?
If the original manuals are in the glovebox, look inside for a plastic card (like a credit card) with digits on it- that is the code, otherwise, you will have to take it in to a ford/mercury dealer and they can get it for you (most will charge for this)
I found the code (1997 Grand Marquis) right on the lock system control module which was inside the drivers door.
Owner's manual says "taped to the underside of the trunk lid".
just ran outside opened the trunk up its right there, a random sticker with 5 digits on it….
look in the trunk on the drivers side latch.shud b a five diget num on it .thats the door code
On the passenger side of trunk lid about eye level when the trunk is opened.
