Door Keypad Code

I recently purchased a 2004 Lincoln LS and have been told several places to look for the Factory Code for the Keypad and have yet to find it. Just curious if any other owners could direct me to the correct location.

Any information would be greatly appreciated.....
 
RE: Door Keypad Code

Thanks for the response, unfortunately I had looked in that location already with no luck. Someone also mentioned that it may be located inside the driver side door. Can anyone confirm?
 
RE: Door Keypad Code

I currently have a 2003 LS, and I took the drivers door panel off, and I could not find it anywhere. I would not waste your time.
 
RE: Door Keypad Code

We purchased today a 2005 Lincoln. After the deal was finished, the salesman told us we would have to pay $100.00 to get the code for the keypad. If you can get it from the original owner, that is good. But in this case, we bought a car that had been bought at an auction. I forgot who they said we had to contact to get the code. I was so irritated by this time that I wasn't listening very good. You have to have the original code to even put in a new one. This is one definite mark against Lincoln. THe keypad was one of the main buying points for us, but if we plan to use it, we have to pay $100.00 which will really urk me. This is the reason some of you can't find a code in your car any where THERE ISN"t ONE

RE: Door Keypad Code

Several years ago, I saw online at a Taurus SHO site, instructions for changing the factory code for the keyless entry and among the instructions were details to find the original code.

Not sure if this would still work on the latter model FoMoCo cars but it might be worth a try. Especially if it will save you $100 and only want to find out the factory code..

Changing Keyless Entry Factory Code

It used to bug me that I had to reprogram my SHO's keyless entry code every time I got the car back from the shop. This is annoying because I don't remember the factory code, and I never remember how to reprogram the darn thing. So, I decided to change the factory code to my personal code.

NOTE: This procedure was done on a 92 SHO, but it probably works on any Ford with keyless entry. And, undertake this procedure at your own risk. It worked on my car, but that is no guarantee that it will work on yours. Also, you need to be able to solder to complete the procedure. If you can't solder then find someone who is competent at soldering to do the work for you. Finally, you should ground yourself with an ESD strap or other means while handling the printed circuit boards to avoid any electrostatic discharge damage to the board. I doubt that anything of the board is static sensitive, but its always a good precaution.

Items required:

A phillips screwdriver.
Five 5.1K 1/4 watt through hole resistors.
Solder Iron.
Solder flux and solder.

The first thing you need to do is remove the keyless entry control box. (I'm told the official name is the Illuminated Entry Actuator/Electronic Doorlock Control Processor, but that is too long to type.) This is located in the trunk of the SHO on the left side of the back wall.

There are only two screws holding the box to the trunk, so it is pretty simple to remove.
Next, disconnect the two wire connectors from the control box.

NOTE: Your electric locks won't work without this box installed, so be sure to manually lock your doors if you go anywhere before you get the box reinstalled.

Now that you have the box removed, you can remove the circuit cards. Just flip down the side of the box and the cards should slide out easily.

There are two cards inside the box, and they are attached with a ribbon cable. You need to work on the lower card, so bend the top card to gain access to the lower card. (Don't worry, the ribbon cable is flexible.)

If you hold the cards with the edge connector of the lower card to the right, you will see the IC (big rectangular black thing) at the bottom of the card. Directly above this IC on the right side are five horizontal resistors. They are what determines the factory code.

The top resistor determines the first number, and each successive number is determined by the next resistor down, so the last number is determined by the resistor closest to the IC. Here is how the resistors determine the code. On the right side of the resistors are five possible solder points. The solder point closest to the right of the card is for number 1/2 the next one to the left is for 3/4, then 5/6, 7/8 and finally 9/0. Below is a example drawing with a factory code of 31936.

So, if you want your first number to be 1/2 you need to solder the top resistor in the far right solder point (always leave the left side where it is.) If you want it to be 3/4 you would solder the right side of the top resistor to the second solder point from the right and so on. This is true for each resistor for each number. All you need to do is remove the five resistors and solder new ones in the correct solder points for your personal code.

Once you have the resistors replaced put the cards back in the box and plug in the connectors to check out your new factory code. If it doesn't work, you probably have a cold solder joint. Just resolder your resistors. Be sure to use electric solder flux for a good solder joint. Also, it is a good idea to clean the wire connector contact points with a pencil eraser. This will remove any oxidation which can lead to intermittent operation.


 
RE: Door Keypad Code

:7 I told you yesterday about the ordeal with the dealer telling me I had to pay $100.00 to get someone to hook a computer to my car and find the code to the keypad. Well, today I called the dealership and asked for the manager. I told him what the salesman had told me, and he said all I had to do was to bring the car back over and they would be glad to put the computer on my Lincoln and tell me the code. So if any of you have bought your car and don't know the keypad code, contact your dealer or anyone you know who has a repair garage with a diagonistic computer. It is as simple thing that can be done very quickly. I was absolutely not going to pay $100.00 to have my car hooked to the computer when I had just purchased it there. Let your fingers do the walking and contact your dealership. Shhirleyb
 
RE: Door Keypad Code

Shirley's right on a couple of points:

The factory keypad code is stored in the DDM's (Driver's Door Module) non-volatile memory (meaning it can never be erased) and easily retrieved by a dealer or anyone with a scan tool that has multiplex capabilities.

If they want to charge you a hundred bucks, throw a shitfit or go someplace else. It takes five minutes; we usually do it for free.

Now, if you want to get it yourself, there's a label on the DDM that has its part number and its keycode.

Yes, it is inside the driver's door!

Lastly, the factory code can be changed to anything you want using exactly the same procedure as the Mark VIII. That's written up quite well in LOD's FAQ/Tech section.
Your new code IS volatile, meaning it would be erased if the DDM lost electrical power, ie: car's battery went dead or was disconnected.

There's one step that may be different: if your LS has Personality Memory, after entering your new 5 digit code, immediately press 1 or 2 to associate that code with Driver 1 or Driver 2.
If it's done correctly, your LS can have:
One keycode for you that will put everything into your positions,
One keycode for your husband,
and the DDM's code, which will always stay the same unless the module is replaced.

Use any one to open the driver's door.

Use any one and press 3/4 to unlock all doors.

Use any one and press 5/6 to open the trunk.

I was in a rush yesterday and posted my message without proof reading it!

I meant:
After entering your new 5 digit code, press 1/2 for driver 1 association or 3/4 for driver 2!

One last thing for anyone reading this thread:

This electronic keycode retrieval is not just an "LS Thing". (Almost) every Ford/Lincoln/Mercury product with an OBDII network is capable of this.
 
RE: Door Keypad Code

Hey, Frankie X--

Can you please either PM me or send me an e-mail?

I would have sent you a PM or an e-mail, but that information isn't in your profile.

I need to correspond with you privately about an issue.

My contact information is in my profile.

Thanks!
