Q: Broke key triggers anti theft system on 2011 camaro.

Broke key trigger anti theft system, how do I reprogram

My car has 80000 miles.
My car has an automatic transmission.

The broken key set may no longer be giving off the signal saved in the vehicles anti-theft system. If the vehicle cannot verify the signal for the key, it will not start as if someone was trying to steal the car. This is probably what you’re going through and the only way to fix is with a new key that must be programmed at the dealership. Consider a trip to your local dealer if you have your spare keys, if not the vehicle may have to be towed.
