The anti-theft system may not be recognizing your key because the chip inside the key is faulty or has been damaged. Or it may not be reading the key because of a fault in the receiver inside the ignition switch. Sometimes interference from other computer chip keys on your key ring may be interfering with the signal that the correct key is supposed to be sending to the receiver in the ignition switch.
One of the protective measures that is designed into today's anti-theft systems is that only new car dealer
Personnel with factory scan tools can access the system for diagnosis or repair. So if you have a problem with a factory-installed anti-theft system, it will most likely mean a trip to the dealer for diagnosis and repair.
Call a tow truck and have your car towed to the dealer for diagnosis and repair.
Reprogramming can only be done by a dealership technician using a factory scan tool, or by an authorized locksmith if you can find one who can do computer keys. The typical charge for this may be $75 to $150 depending upon how long the procedure takes.
