My FOBIK is only working intermittently. I changed the battery (twice) and either the key isn't working, or the receiver isn't picking up the signal consistently. It's killing me. I will try a reprogram, but am trying to avoid the dealer.

You should be able to open the door with the mechanical key blade that is inside the FOBIK, once the door is open, the FOBIK should NOT have any problem starting the vehicle.

Get a battery for the FOBIK and replace it. I have pulled the battery out of my FOBIK just to test it, and yes, it reatains it programming to the vehicle when you swap batteries.

The vehicle start and remote keyless entry or two different systems contained inside one FOBIK. The vehicle start is done by an RFID chip that is in the FOBIK, that does NOT need any batteries, the WIN (Wireless Ignition Node) uses RF energy to energize the RFID chip and power it, to interogate it and allow it to start the vehicle, if its been programmed to the vehicle.

If the battery goes dead on the FOBIK, its just the door lock/unlock (plus the rear window open/remote start if equipped) that won't work and thats why there is a mechanical key hidden in the FOBIK.

Its possible, like ColoradoKing has, it might be some sort of reception problem with the radio signal from your FOBIK. A weak battery will make for a weak signal out of the FOBIK, but there is an antenna and receiver in the vehicle to receive the FOBIK signal, that could be the problem and even a weak battery in the vehicle could be behind that, BUT, I'd "think" if the vehicle battery was too weak to receive a FOBIK signal reliably, it also would be too weak to start the engine.

The Jeep is still under warranty, so I'm going to get the dealer (stealer) to check it out on Monday. I'm hoping they'll toss us a new FOBIK and let us keep the old one, as we've lost the other spare key... Fat chance, but I'm a dreamer. Will post the results once we get the vehicle back.

Yea, Dealers charge as much as $266 for a new FOBIK, fat chance of getting a complimentary one. Anyone that has bought a used Chrysler Vehicle, even from Dealerships, only gets one key. The prevous owner loses one of the originals and won't pay the high price to replace it, even the Dealerships won't pay the ridiculous price to provide 2 keys like they are supposse to.

Funny thing is, Chrysler pays $8 a unit for them, then sells them for $266 only through the Dealership Network.

Turns out the FOBIK was toasted (fail code B1A08 RKE FOB PERFORMANCE). They provided a new one at no cost, but I still have to see if I can find the one my daughter lost...
