Contact Needswings or SOS - you will need to yank the ECU and SKREEM and send them to them. They can make a key for your car, but I'd go with a SKREEM Delete, where the car no longer needs that little chip to start. This decreases security a bit, but our cars are not big theft targets anymore. This way, you no longer need the RFID chip and the car starts just by turning the key.

I understand this will cost around $450-500 but once you do this, you are DONE with SKREEM issues forever.
