2007 Towncar Door code not working

[faxjax]

Hello Folks,

New to the forum and Lincoln ownership.

Purchased a low mile 2007 a couple weeks ago, the factory Door Keypad code was in the book, however when I enter it nothing happens. I hit the last 2 numbers and the doors lock though.

Any idea's, as to how I need to proceed? I removed the trunk lift arm covers to try and verify the code is correct however, there is no stickers on either of them. The Code card appears to the official Ford card with the car only having 52K miles, I believe it to be correct.

Is there a way to reset the car code to make sure the factory code is responding, Like rebooting a computer? I hesitate to unhook the battery as for all the other things that get rebooted, transmission adjustments...

Any help would be appreciated.

The code might have been changed.
The code on your year is not written anywhere.
You can download a program called Forscan to retrieve the code.
You will need an OBDII adapter as well.
On the Forscan site they have some recomendations for adapters.
Or, you can go to a ford dealer and they can pull the code.

I have a cheap OBD Scanner, wonder it that will tell me anything?

Hi, faxjax.

Yes, but nothing that will help you.

My first guesses are that either your drivers door module (DDM) has been changed, the existing DDM has gone bad, or your keypad has actually gone bad, based only on what you are describing.

After you've entered the five digit code, have you tried opening the trunk? Or having all doors unlocked? Does the drivers door itself unlock electronically via the fob or on-armrest rocker switch?

If the lock actuators are good, and the keypad only locks the doors using the 7-8 and 9-0 buttons, then either one or more of the first three buttons on the keypad are bad, the DDM has been changed, or the original DDM itself has gone "bad."

If you run a Carfax report, it may tell you if the DDM has been replaced. If the car was "local" to you for its whole life, you might also ask the original servicing dealer if they replaced the DDM. If so, ask if they saved the "new" factory keyless entry code.

The factory keyless entry code may be on a sticker on the DDM itself. You will need to remove the door panel to confirm this.

Or, you can download Forscan as @alumarine suggested and buy the correct adapter for the computer you install Forscan on and read it that way. You should be able to test the keypad itself with Forscan, but I haven't used it yet, so I would defer to others who have.

The Ford factory software and hardware interfaces are also available to the general public. But if you have to ask how much they are, you aren't interested.

Good luck.

No, it won't. And if someone had programmed a new user code, the factory code would still be active. It is possible that the DDM (Drivers Door Module) is flaking out. Does anything else not work (seats, windows, locks)? It is also possible that the DDM has been replaced, which would give you a new code. I guess it is also possible that the door keypad has a bad button. Short of going to the dealer (and possibly costly), FORSCAN can find the code for you, as Alumarine mentioned. I've never used it myself but have heard of others doing so. Good luck and welcome to the world of Lincoln!

I had a phone call in the middle of typing this and in that time I see Brian already said some of the same stuff.

Thank for the info, I will have to do some more research

The drivers door locks and unlocks with both the keyfob and armrest rocker switch.
So either the keypad is bad, or the master number is different that what I have I guess.

Will likely order a the ford scan tool and see what it says as I am not excited about removing the door panel if I don't have too.

Thanks again

You might consider getting an oil change at your local Ford dealer and casually mention that you can't access the keypad code. Don't tell them you have that card. I did this on my first Lincoln Town Car and they retrieved the number for me during the service, no charge. Only takes a minute to do. Downside is they might do it, out of the goodness of their heart, or they might try to charge some outrageous price for the retrieval. In this case, FORScan is your friend. Welcome and good luck!

Hi, faxjax.

The Ford factory hardware, interface, computer, and software package is $2500 or so to buy plus $900 per year to use. And the $2500 (AFAIK) does not include the first year!

At least some of us will feel compelled to bite that bullet sooner rather than later. The newest cars covered by this forum are already nine years old. The oldest ones already qualify for "antique" plates everywhere in the United States. The dealerships will (and in many cases already have) lost any expertise and desire to work on them, and the factory support is fading. If we want something done software-wise on our cars that Forscan can't do, we'll eventually have to do it ourselves.

If you have one or more friends who also own a rear-wheel-drive Ford, Mercury, or Lincoln, so much the better. Or if they own a Mustang, or just about any Ford product older than 2014 that they actually want to fix and keep running. By either "going in" with them on the cost, or having them pay you to help them by using your Ford software on their car, you can reduce the cost you pay out-of-pocket and never get back in order to have that particular tool in your tool box.

If you plan on doing almost all of your own work, the factory software should suit you just fine. You will no longer fear the dreaded DDM, or any other re-flashable module, because you will be able to flash them yourself. You will be able to diagnose almost every ailment your car will ever have. And, you will never again have to pay $185 plus the cost of the key to replace a key on the car.

If not, you probably ought to just get Forscan. You may not be happier with it, but you'll be $3000 or so less miserable.

Good luck.

I'm resurrecting this 5 year old post because I'm having same problem - factory code not working. Car is a 2010 Town Car. Here's the catch.. I read the code from the DDM using Forscan Lite. Doesn't work. The code the seller gave me works. Keyfob works. Lock/unlock on the door interior works. I've verified in forscan that each button on the keypad is responding and reports correct number being pressed. Pressing the last 2 buttons locks the doors. Why is the factory code reported by forscan completely ignored by the car when I try to use it?

I believe that a new door code can be programmed into the DDM, but I don't know if doing so invalidates the factory code from being used going forward

msu-dawg:

Your troubleshooting appears to cover all possibilities. The only thing I can suggest is that you disconnect the battery for a half hour or so, reconnect and then re-read the factory code with Forscan. I've never heard of that helping this particular situation but can't think of anything else to try

Is the code on the keyless module the same as FORScan?
