However, as time progressed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.

The key chips in the keys have a specific serial number, which transmits signals to the receiver inside of your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes are similar then your car will begin to start. If the codes don't match, then your car will not even start. This is the reason you should keep a spare car key, particularly if your system is based on transponders.
