No, just keeps the FOB from working, car will still start with key.


I'm assuming you mean the remote-starter installer stuck a copy of the master key inside the vehicle as a means for bypassing the PATS (passive anti-theft system)? If that's the case your vehicle has been without anti-theft protection ever since. If you ever get a car/truck stolen, the insurance company asks if any remote-starters have been installed and how they were installed. Having that key permanently hidden in there for the remote-starter is a cheap way to bypass the PATs but it will not keep your car from starting if a battery dies in the FOB.
