I went and did it, washed my key fob. While it is nice and clean it doesn't work. Does anyone have a working key fob from a wrecked car? I can change the transponder and key over myself. It is the circuit board that is bad.

 

There are a bunch of the on eBay. Searched "crossfire key" narrowed down by used. There is even a lot of 7 for $95. I bought new case for both of my keys $5 apiece

 

I saw those, the cases are not great. They would be a last resort.

 

I read on a forum somewhere that you can soak the board in rubbing alcohol and that might bring it back to life.

 

Hmm.. I love the replacement I got.. Alarm button was wasted on the OEM, and I got one of the new cases that were in black.. has the recessed logo area where I put my little OSU sticker (Andrew badges). Filled it with high dollar clear nail polish, and has far outlasted the OEM sticker treatment. But if your circuit board is bad, it's my understanding nothing short of a "new" key is going to actually work right. A used one will basically get you right back to where you are now with a different case.

 

You can't use the old transponder and a new circuit board? The transponder couldn't have been hurt I wouldn't think. Are they matched as a set? The circuit board just does the door locks and alarm right? I am going to try and start it tomorrow ( at Fire Station today ) without the circuit board in it to see if the transponder will communicate with the car. The circuit board and the transponder did not look electrically connected. The circuit board was corroded in many places, the batteries tested 2.96v.

 

Your fine with the key and transponder. You could actually epoxy the transponder to the key and be done.. You won't have any results with a new (used) board installed. The boards (electronics) are not reprogrammable to another car by an individual. They are "open to programming" when new, thus the two button programming threads (when new) and programming after battery install. You will note also in these fob threads of having to change out the electronics.. just for this reason.

 

Larry .... Don't know if it will help, but if you have another key fob that works, I would try to dismantle the "wet" fob the best you can without physically destroying it, and then wet it again with water to flush any detergent, and then "pickle" it in WD-40. As you know WD-40 is water displacement stuff. Dry it and reassemble, then see if you have re-incarnated it. Just sayin .....Good Luck

 

I understand now, thanks for the clarification. When I put the fob back together I just left the Circuit board out of it.

 

I can give it a try as I won't be out any more than I am right now. Thanks Howard

 

Hey Larry .... just pickle the circuit board. Didn't realize you had it out already.

 

+1 .. "Reviving" the old board.. or new key - fob purchase will be your only options for a functioning FOB. Your key and ignition - starting should still be just fine with the chip still in place.

 

I cleaned it (soaked) with rubbing alcohol and cotton swab. then let it dry for a few days, have yet to reinstall it. The key does start and run the car ok. One thing I didn't know is the key locks and unlocks both doors at the same time

 

Howard should I still do it with wd40?

 

Is it actually true that the circuit boards are one offs for a particular car? I think that may not be true.

Is it possible that the SKREEM will accept any similar transmitters signal after they have been synchronized? Synchronization only being possible when the chip which has been specifically precoded to the cars VIN and recognized by the SKREEMs matching code.

The transmitter sends out an arbitrary rolling signal just like garage door openers and if your garage door transmitter fails you can buy another and sync it to the receiver no problem.

 

Larry ,,, you may not have to. The wd-40 is only for water displacement. Soaking it in alcohol and drying it, should have accomplished the same thing, and you might be OK. I would reassemble it and try it. You might have to do the key fob sync thingy, by inserting key in ignition and turning to "on" and pressing lock and unlock in some sort of order. Someone chime in here. I could be wrong on this point. Senior moment or brain-fart (whatever, LOL). Let us know

 

hmmmm... interesting..

Chrysler crossfire key fob will not work to lock, unlock or - Fixya

 

I wish we knew for sure which way this really is before I am tempted to get a used key somewhere and try it. They are a little salty though for something that may or may not work.

 

I hear ya.. "thought" about taking my fob to the wife's car and see.. then thought better of it just in case.. LOL.

Don't want that Chrysler/Mercedes voodoo crap biting me in the butt..

I know we did buy a fob for the wife's Tahoe a few years back. We only had the one and was at a flea market. Bought it and he came out to the truck and programmed it in through the user dash interface. Just don't know if the designers were this nice too us on ours though.

 

I finished this yesterday, I just got through testing it. It now works the door locks just fine so all is well again the fob is repaired. It appears that a good water soak is not terminal after all.
