[Tech II]

I'm a little confused....are you saying your old key will open the door AND start your vehicle?

But your new key will open the door, but it won't turn in the ignition lock cylinder, or it will turn in the lock cylinder, but the car won't start?

If it's the latter, does it crank over and not start, or it doesn't even crank over?

If the key turns the door lock, but doesn't turn the lock cylinder, you have the wrong key....

As for this particular key, it is a PassLock key.....it is basically a blank key, and does not contain a resistor or a transponder....
