I tried using the key and waving the circuit board by the ignition and it worked, you can take it away after a few seconds and it will stay running.
Does your key have a metal key "blade" with the bumps and ridges to use in a mechanical lock?
Does your key have a just a blunt black plastic plug that is put in the ignition?
The former is a Transponder Key, the Laters is a RFID key.
From what your saying it sounds like the transponder chip or RFID chip is on the circuit board. Starting the vehicle with an unauthorized key, non-transponder/RFID or wrong transponder/RFID will do exactly what you describe. Moving the circuit board in close proximity to the ignition module makes it appear to be the transponder in the key.
If you have a locking ignition with Key Blade type ignition, you can tape the one transponder you have to the ignition and be OK because you still need a key with the right profile cut in the blade to start the car. If you have the later RKE fobik, this is NOT a good idea, because if the RFID chip is taped to the ignition, any plastic block the right shape will start and drive the car.
You could tape the transponder/RFID chip unto the ignition module under the dash, so its out of sight, likely it will work just as well.
If you only have one working key, the dealer can make a 2nd working key for you, you'll have to pay them for service to do it. Then you can make all the additional keys you want yourself, using a procedure that has the car program the keys itself, I think there is a limit of 8 keys total, including the keys the prevous owner lost, as long as you have two valid keys to start the procedure.
In 2010 they killed that feature, and in 2009 for a lot of other Chrysler Cars, if you have a 2010 Commander, like me, the only way to get key copies made is to go the dealer and pay them to do it. The Dealer will charge hundreds of bucks for blank keys, you can find them on ebay for $30. Just make sure you get the right part number and the key is NOT used, it has to be new, used keys can NOT be programmed again for another vehicle.
Dealer employees got caught making key copy's for criminals to steal the cars, using the self-programming feature. So Chrysler punished the dealer by removing that feature, so the dealers make a lot of extra money that the customer loses by having to pay the dealer for what they used to be able to do themselves. Some punishment, huh?
