I recently purchased a 2008 Navigator L and the entry code card was not with the vehicle. Is there a way to find this in the vehicle w/o taking it to a Lincoln dealer? I have heard that these codes are sometimes hidden in the vehicles at certain locations.

Thanks in advance for any help.

 

might be diffrent or i just might have gotten lucky but i found mine on the drivers side rear hatch hing

 

Here is a reply from an older posting that might be of some help.

So, you know those cars with that keyless entry pad? The one under the driver's side handle? Well, if you look closely you will see that there are really only 5 buttons, labeled "1/2", "3/4", "5/6", "7/8", "9/0". In an effort to avoid a little confusion, I'm going to call those buttons 1, 3, 5, 7, and 9, respectively.

A little experimentation will reveal that, if the code is 11357, and you type 5113579, the door will still open! This means that with 7 characters we managed to try out 3 sequences - 51135, 11357, and 13579. After the inital 4 numbers (which sort of primed the pump) every digit tries one new sequence. Since there are 55 length 5 sequences of characters from an alphabet of size 5, we know that we'll need to try 3125 sequences total. With our intuition from above, we would hope that we could find a sequence of size 4 + 3125 (priming the pump, followed by one new sequence every keypress). It turns out that a mathematician named de Bruijn has already done all of the hard work for us on this one, and all of the relevant math can found under the names de Bruijn sequence and de Bruijn graph. But I'm not going to talk about math any further here. Right now, I am going to give you a sequence of minimal length that, when you enter it into a car's numeric keypad, is guaranteed to unlock the doors of said car. It is exactly 3129 keypresses long, which should take you around 20 minutes to go through.

Happy hacking!

 

Start with your drivers window down, and door locked when you do the above method. When your door does unlock from the above, back up 5 numbers, lock your door and re-enter those 5 numbers, it should unlock, and that will be your code. If not then back up 15 numbers and try it from there. Took me a couple tries when I did it.

I say start with the window down so you can lock/unlock again with out opening the door etc.

 

No, the older Expys 06 and older had them on the SJB, the 07's and up are not there. You have to goto the dealer and have them retrieve it via computer.
