I just purchased a 2002 Mercury Grand Marquis. Seller did not have keyless entry pad code. Somebody told me to look for the code on the trunk hinge. Not there--previous owner must have removed it. Somebody else told me that to program a new code I must know the last one. Local Mercury dealer told me, for $25, they could put my car on a computer to find code. Is this the only solution?

While it would certainly be worth $25, there is one other possibility...check the owner's manual, it may have the factory code in there...many folks do not read the manual, and never learn how to change it to their "favorite" number, so the number may just be the factory code...
Also, the factory code may be 1,2,3,4 or 5,6,7,8...then reset it to your code...it might work...or $25...

Car did not come with an owner's manual either. All I know is that the keyless entry pad code is 5 digits long. I bought this car from a Lexus dealer and was surprised they didn't have the manual or code. (On the other hand, my daughter bought a used BMW from a BMW dealer, and she did not get an owner's manual.)

While I am never one to waste $$$, mine or yours, I can't really complain of $25 to find out the number...$100 or more, I would scream to the heavens, but $25???...pay it and get the number and reset it and get on with your life...

If it's like the ones for the new Five Hundreds, and I think it is, the original factory set number CANNOT be changed...it is permanently set (and it is NOT something simple like 12345). The second number is one you can set yourself to anything you'd like, but you must have the first number to change the second.
I agree that $25 seems VERY reasonable to find out what that number is.

Come to think of it, you are correct, IIRC...the factory number is permanently assigned, and your "favorite" number becomes an additional number used to open the door and trunk...so, with a VIN, any Ford dealer can always find the factory number, then you can program it with your extra number...
Thanks for that reminder...my original thinking on that procedure was wrong, but I stand by my statement that it is worth $25 to get it...

If it is not too late, open the deck lid and look under the package shelf for the White sticker with the Black numbers. Hopefully it is there which is where I found one on our T Bird.

I have a 2000 MGM that has become my pride and joy since buying it just under a year ago. I've been lurking here since just before I purchased it (this forum strongly influenced my decision) for tips and tricks. Now I have one that I can't seem to find an instance of it having been answered before.
I came home with a nasty sinus infection the other day and forgot to lock my doors before I went in the house (15 years in the security industry preaching this stuff to clients...). Some time over night the local hoodlums raided my car for goodies. They got some unimportant stuff like my cellular headset and a couple of items I'd picked up at a garage sale, but they also took my user manual from the glove compartment. While I do miss having that cool Mercury emblazoned booklet in there, I'm more concerned that the factory unlock code card was in there. Having watched the neighbourhood kids for years I don't think that they're smart enough to come back again (and again) but I'd prefer not to take that chance. Has anyone ever had to change the security module in their car? I realize that the factory code isn't changeable but I presume that installing the module from another car may address my problem. Is this possible? Is is expensive? Am I grasping at straws?
