Will the ignition and computer of a 95 Grand Marquis work in a 2000 Grand Marquis

No. If you plan on this, you also need the key, ignition lockset, BCM/GEM, Instrument panel, and PCM. If you want to radio to work, you'll need it also. Not sure, but I believe the years you can use are 99 to 03. When changing a computer(PCM), you need all the security with it. Otherwise it is off to the dealer to have it programmed.

How do I reset the door lock code on a 93 Mercury Grand Marquis if I don't know the current code. I bought the car from a family and the owner had passed away and they don't know the current code.

There is a master default code that will always work no matter how the personal codes are set. Codes are 5 digits and should be on a card hopefully in the owner's manual packet. If you can't find the card, any Ford dealer can retrieve the master code for you. Even if you knew the previous owner's code, you'll need the master code in order to program a personal code of your own.

Good luck.

I cant find the factory five digit code to reset my keyless door panel. What do i need to do or how can i reset it. This is a 2001 Mercury Grand Marquis.

This number is usually inside the trunk jamb. It's printed on a sticker. If you've the owners manual, there's also usually a card with the number on it. If you know your original code and are trying to reset a newer code back to the original, disconnect the battery for 10min. Loss of power will revert key codes back to original factory setting.

My door lock remote will not function and new

have you tried to press/hold lock button for 30 secs.
the code changes everytime you use the remote so that only your remote unlocks your car,not everybody elses.the key has a code inbuilt into it so the car will only start with your key...(this is dealer programmable)
