As time went on and technology improved and improved, automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys and are designed to make it harder for thieves to start the vehicle.

The key chips inside the keys have a unique serial number that sends a signal to the receiver in your car. When the signal is received it is compared to a code stored in the car keys programming's computer. If the codes match, then your car will start. If not, it will not start at all. This is the reason you should keep a spare car key, particularly if your system is based on transponders.
