I have a 2003 Jaguar x-type. It has just over 100,000 miles on it. It has currently be at the dealer for 3 weeks because the security system is telling the engine that it is being stolen. The dealer said it was the ignition barrel switch security transceiver. We found the part in the UK. They put it on my car and it did not work. Any ideas on how we an get my car started again
