I bought a set of handles with a drivers keyless entry handle to add to my '04 XLT. I have the pre-wiring in the door and truck came with keyless entry system. I got the handles of an 07 FX4 and did the drivers door handle swap first to verify functionality before getting them painted. The key pad does not operate. There is no life to it at all. I've studied the connecting ends, pins, made sure of connction, pulled the rear seat to verify i have the BCM module or whatever it is. Nothing, no power to it. Any ideas?

The module behind the seat had two harnesses plugged into it. There is a slot for a third harness but there was not another plug in any visual area. Guys with sound systems in your trucks and a keypad door handle, is this how yours is setup? Do you only have two harnesses plugged in like I do?



I don't have a voltage tester so I can't quite test the handle itself or the ports. If I can't figure this out I'll have to have the dealership do it.

 

Mmmm I'd recommend buying a cheap multimeter and testing it. Would be worth a shot over going to a dealership.

I may have some old audio installation pics hanging around. I think they got deleted, though, but I'll check.

 

Found one old cell phone pic. Of course it's difficult to tell.

It doesn't look like there's a third harness plugged in....

Darren- when you say that you have keyless entry system, I am assuming you mean the remote entry system. If you didn't have a keypad before then you didn't have a "keyless entry system". I have a keypad (which I added shortly after buying the truck in '04). When I tried to operate it, I also found out it was dead. There was a ton written about it back then for the same reason that I had to deal with it and you are having to. The '04's, and maybe into the '05's, Ford did not "turn on" the recognition of the "keyless entry" in the PCM, (or possibly the BSM) if it was not factory (as built). That's the reason it doesn't work. You can have a Ford dealer "turn it on" (through the computer hook-up), but I chose not to because they wanted an hours labor to do it, at $100. an hour. I had the complete printed instructions from Fords own shop internal site, but that didn't make any difference.
If you want to spend the money on having the dealer hook it up and turn it on, I'll send you a link for that info. That's the ONLY way it's going to work. Ford pretty much started to "turn 'em on" in most all of them in maybe sometime in '05 whether they had the KE or not. Mine came with the code card in the glove box packet, but it's worthless without the "turn on". You know right away if it is "turned on" or not because if the keys don't light up, it's not turned on.
One other thing I caution about, don't go using a test light or voltage tester on ANYTHING that you don't know doesn't go through a computer (pretty much everything does now) because you can damage the computer and cost yourself a lot of money. I use a cordless "computer safe" test light on pretty much anything anymore, you just can't test the way you use to.
P.S. even most dealers don't know the instructions for the tech to turn it on are on their own internal site.

 

. I did search but that never came up. Well thanks!


If you would PM me this link to the guide I would be greatful. If there is a method of activating this module for my '04without buying a newer model module or paying dealership labor lay it on me. You can PM me the guide if you have one or PM me for my email.

Thanks for the voltage tester tip also.

 

Went to the dealer, they told me there was no keyless module to activate.. Kind of disappointing. May need to use a module out of a truck that came equipped now.

 

Darren here is a pic of the module in my 07 that came with the keypad from the factory. Only has two plugs in it.

 

Well. Same color harness heads, same style module, mine is just mounted differently. Do you have the part# for it? I may compare it to my '04s without keypad and see if I can score one cheap.

 

try and zoom in on the pic and see if you can get the numbers off it. If not, I'll try it on the original pic that wasn't downsized to load it in my gallery. Never mind, here it is.

7L3T-15604-CK

 

Would be cool if you could try that. I wanna say its 7L3T-15604

Edit:

Haha good guess, thanks!

 

Darren, I'm not questioning the judgement to buy a BSM from a later one that would be activated already. I don't think they get more than $100. for one, but what is wrong with the wing-nuts? You posted the picture of your VSM, at least I took it to be your VSM, THAT IS THE KEYLESS MODULE!!! Just love the dealers that hire the mentally handicapped. I guess they have to eat too huh? Go back and tell them to show you what a Keyless Entry Module looks like. Just bet it bares a STRIKING resemblance to what you posted in your entry post. Bet if they actually WERE able to read and operate the shop computer, they wouldn't have any problem switching on the VSM (vehicle security module) that you ALREADY have! (the XLT came standard equipped with it.) The only thing that was optional was the door keypad which operates the same module that your remote operates.

 

That was exactly what I was thinking. On 04 - 05s it needs activated. Saying that there was none to be fou d confused be. Unless the wiring was cut in half somewhere but even then my remotes work. The dealer never screwed me over yet. Might have to try a different dealer, or go back with a rougher attitude.

 

Bluejay had this problem trying to get his keypad to work when he added LT handles.I believe they added a ground wire in the BCM. https://www.f150online.com/forums/3634979-post22.html

I was lucky when I installed my LT handles and added the keypad.I plugged it in and it worked.

 

Darren, i have serious questions about that dealers ability to check the air in your tires, much less deal with the Keyless entry "turn on". That was the whole purpose of my giving you the link for the Official Ford rundown for the shop tech's to turn it on. I figured if you printed a copy off from that link and went with it in hand, it should take all the work out of it for them. I seriously don't think they'd be able to do it, even with the copy, if they tell you you don't have the part (VSM) that came STANDARD on ALL '04-up XLT's. RKE was standard on the XLT and that is what the Keypad also operates through. As you can see from the many posts, Ford DID start turning the Keypad on in the VSM, even if it didn't have the option, by sometime in maybe '05, but definitely by '06. My '04 didn't have the keypad option, but it DID have the card in the glovebox packet with the 5 digit code.
