The screen module is the only thing that was replaced and reprogrammed in order to start your Crossfire again? Thanks for your input, I have mine seating at the shop.
A key not unlocking the car does NOT mean the SKREEM is bad, it COULD be bad, but I'd put the key in the door and unlock it manually and then see if the key starts the car, and go from there.
To unlock the car, the battery-operated transmitter in the key fob sends a signal to the SKREEM which then gets on the CAN but to tell the security module/pump to unlock the doors.
To start the car, the skreem communicates with the RFID chip in the key fob to verify it is a legitimate key.
There are two devices in the fob, if the transmitter or it's battery is bad, the car won't unlock, but the RFID chip will still start the car once the key is inserted in the ignition and the RF ring activates the RFID.
