Using a Key Programmer

Certain vehicles come with electronic immobilizer systems that prevent theft by stopping the engine from running without the correct fob or key. This is done by having the car's system examine to ensure that the fob or key has the correct digital signature. If it doesn't it will shut down. This kind of system has been proved to be effective in reducing automobile theft and was made mandatory for many models of cars by the manufacturer.
These systems can be controlled by a module that is installed in the vehicle's engine compartment, instrument panel or ignition lock. In some instances, these modules require special keys that are created by a professional to work with the anti-theft system. This is typically done by a dealership or locksmith through a computer.
