Whats this mean?
Is there a way to reset the security system? or any info would be great thanks
If you changed the ignition cylinder and therefor have to use a different ignition key, the VATS system is preventing the car from starting because the new key doesn't have the correct resistance to match what your BCM has in memory. No, it can't be reset. You'll have to get a new key that has the cuts matching your new key but on a blank with the same resistance as your old key.
