Ignition lock cylinder

On some cars the key must be re-programmed to the car which only the dealer can do, your car is right on the line from when they started doing that so you might be okay, let me know how it goes so we can help others.

Ok the key is a transponder key and the VIN starts with a 1. Is there anyway that you know of that I can program the new keys myself?

If you have a new key you will have to do a re code, if you recoded the lock to suit the original key there should not be a problem as long as the key reader is also original and matched to the key.

No, the ignition lock cylinder that I got is a aftermarket import direct. It did not have the key code reader on it so I had to install the original one from the defective key lock cylinder onto the new one and the green key light comes on when you turn the ignition on and then it blinks and does not go off until you turn the ignition off. I have the original keys (the grey one and the black one) that originally came with the car and I have the defective key lock cylinder. The engine turns over it just does not start. After I replaced the key lock cylinder I had to input the anti-theft code in the radio and it works now also. Please help, I am just baffled on what else I can do other that call the dealership. I really do not want to do that if I don't have too. Thanks

Please let me know how it goes.

Yes the security light is on and it blinks when you try to start the car.

Okay that is the problem, the security light cannot be blinking, can you disconnect the battery for 2 minutes and reconnect it please, once completed close all doors then lock and unlock the drivers door. This should reset the system. If not the transponder and ignition need to be programmed at a shop or dealer please help.
