How to Reprogram Keyless Entry???

Got a nice pre-owned '09 Nav over the weekend. It has the keyless entry system, but, I don't know what the entry code is, and I can't find the little tag in the Owner's Manual that had the factory setting. How do I change the code?

Need to have the original code to add/change code. I believe you will have to go to the dealer to get them to pull the code.

Yes, dealer has to pull the code from the computer. Without the master code, you can't add your codes. I would call them and make them pull the code.

Just had that done on a used Edge. Had to visit the dealer. No charge, but I bought it there.

I know their used to be a sticker in older FoMoCo products with the code on it. It was under the trunklid on my SHO's. I'd think if Ford still did that somebody would have told you where to find it, but you might poke around in the cargo area anyhow. For security purposes, the code would likley be someplace you could lock.

They got rid of that in the 07 and up models. Have to have it pulled by the dealer.

Each vehicle equipped with a keyless entry keypad is programmed with a 5-digit entry code. This code is provided to the customer on a wallet card in the Owner's Literature package. In addition, this code is available through a scan tool.

according to my Repair Manual DVD, the code is still printed on the SJB...which is in the drivers kick panel on the 07+ Expy.


look for a little PCM looking thing. if it's there, there will be a white sticker with a 5 digit code.


if not, then yeah...gotta pay the Dealership

I am gonna check this out.

Hmm. It gets more interesting. Saw this on another forum.

You should find the keypad code on the back of the (SJB) Smart Junction Box located behind the front passenger kick panel. Remove the panel and remove two bolts holding the SJB, once you do that you should be able to read the number (small print) on a white sticker, look for a 5 digit numerical code.

Crap, I didn't bring my tools to work.

There is extensive information on the "Supercoupe" sites on the keyless entry modules and how they work. Probably on the SHO sites as well, just have to search.

I have saved and printed the info for the supercoupes----BTW, anyone want to buy a 92 with the usual blown head gasket issue?

The keypad wires to a control module that has 5 resistors on a PWD board. it is the placement of the resistors on this board that determines the sequence of the buttons. Anyone with some wiring skills can rearrange the resistors for their own pattern. If all else fails, the pattern can be determined by looking at the resistors on the board.

I am not sure that the new vehicles use the same method, it may be in software on the DT control module now----dont know.

Maybe someone with alldata can looksee if there is any info shown on the modules specs.

it is all programming now benshere...it seems to run about $50 for the Dealership to connect to the PCM and talk via the CanBus network...annoying, but technology is pretty cool

Its been a while since I did anything to do with programing or processors. The longer I am out, the further behind I get "Technologically displaced". I cant help but wonder if that bus can be accessed by some enterprising car nut. I can guess that its the location or access for all the "snooping" info that is gathered, such as data logged for the previous seconds or minutes of driving. You know, all the hype about lojack on new cars. Sounds good, but just wait until it gets used against you.

Might be useful to have a shorting pin to use similar to resetting the bios on a motherboard when you dont want your last few minutes of history to be seen!

Isnt it amazing how people can hack PC's and steal you blind, but dont seem to be able to hack a car system. and its not even a terribly sophisticated system---just proprietary. Oh well! guess I am in a paranoid phase----.02!
