Ok so i took my car to the Ford Dealership, a large and reputable one here to get the door code reset, was supposed to be a easy 30 minute thing, wrong.

after an hour in their waiting room the tech came and told me that his computer system will not reset the code, and he suspects the system is aftermarket and cannot help me further than that, and refunded my money...

This thing is identical to the factory ones in looks, so what i want to know first, is how do i get the damn pad off the door so i can try to identify its maker, and pursue it with them hopefully?

i tried pulling it every direction i can to see if it poped off somehow but it doesnt, and i cannot find any screws in it.

It is functional tho, when i punch in a few bad codes, or hold in all the buttons at once it locks the car doors.

It is on the driver door just above the handle.

Most likely two sided tape and I don't believe this was ever an option on Mustangs. A quick Google makes me believe it was a Ford accessory you could buy and add on later.

If those directions are correct, those things are not secure in any way. I'd remove it and destroy it immediately if it programs that easily.

I've had several of those, on a Taurus and on an F-150. It is the same keyless entry that Ford uses on the F-250 and 350 trucks, and it is quite secure. You need to have the key on to program it to work on your car, in fact I think you have to do the on/off thing a certain number of times. But it you don't know the device's original code, or the 2nd one that was programmed into it, you are screwed....

Note, the comments in the 2nd post showed a link to how to re-program the keyless pad. Those instructions are identical to how to reprogram OEM Ford keyless entry pads on all their cars. You can't do it unless you know the original code, or the secondary code that you programmed in yourself.

Good grief, I missed step one in the directions, lol.

It looks to be useless if you don't know the original code. It is not hard wired like the ones on the Taurus and F150/250/350. This one you have is an add on that is wireless. I don't think it is going to be able to be reprogrammed in the conventional method. I'd ask the guy at the aftermarket Ford parts counter if they are reprogrammable if you do not have hte original code. If not, a heat gun will help you remove it and toss it out.

The ones I had on my Taurus and my F-150 were exactly the same. I purchased them after I got the car and added them with the double-stick tape. Both worked perfectly for years.

I was thinking about your problem on the way to work. There are 3125 possible code combinations. There are (probably) 2 codes programed into the keypad, the original one and a prior owner's personal code that they added. That means the odds of finding a code that works should be about 1 in 1600, and if you get a little lucky, you should get it in the first 1000 tries.

Every one I have ever had has had at least one key that was pushed twice in a row, so that should lower your odds even better.

I bet I could crack the code in 400 attempts or less.

If you go that route, BE ORGANIZED. Nothing worse than cracking the code and then not knowing exactly which numbers you just punched in...

You should be able to get it done in about 2 hours. Good luck!

Oh yeah, after every attempt, hit the last two buttons simultaneously, to lock the doors, that clears the previous 5 keypunches and lets you start fresh.

ok i got it off, and still no branding on the back.

never used one before, how many digits is the code, and after entering the correct code do you wait a second and it pops, or does it open the instant you press the last number correctly.

[trooplewis]

It is always a 5-digit code, the locks will pop up the second you hit the 5th digit if you got it right.
Almost guaranteed your part is a Ford part, I don't know anyone else who made them. Ford sells them in their parts department.

last question, does anyone know if the keys can be repeated or if its just a patern using each one once?

i guess i will just get a new one, this one i cant do anything with, even took it apart to see if there was a code on its circuit board imprinted or something, but nada.

my goal was to hide a spare key somewhere in the car good, and then if my keys were lost, stolen, or broken i could just punch in the code and still be good. and never locked out of the car with the keys inside.

[trooplewis]

Yes the keys can be repeated.

I just bought one of these and installed in inside the fuel door. It's a Ford accessory. It has a permanent factory code printed on a card, about the size of a credit card, that you are supposed to have with your paperwork for the car. You can set a personal code by first entering the factory code. When you set a second personal code the previous personal code is erased.

According to the manual, SK7L2J-19G544-AC, The dealership should be able to retrieve the factory code. So either the mechanic didn't know what he was doing, didn't have the equipment, the device is broken or perhaps the battery is low. It has a permanent battery that cannot be replaced.

the battery actually is replacable, it pops in and out, a nickel sized lithium, getting the pad open is hard, but the battery is slotted just like PC and Laptop motherboards.

MasterX, it is supposed to be a permanent battery because you can't take the thing off the car and then put it back on. If I recall, mine said the battery was good for 100,000 open/close cycles. If you open/close your car 4 times a day, that means it would be good for 68 years.
