As technology improved, more and more automobile makers began to combine electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.

The key chips in the keys have a specific serial number that transmits an electronic signal to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match the car will begin to begin. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key in your car, especially in the case of a transponder-based system.

The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. The code is matched to the unique digital serial numbers in the car's computers. This is to prevent unauthorised attempts to start the car, as only right keys can be used.

The technology is believed to be more secure than traditional car keys because it makes it much harder for a thief to "hot wire" an automobile and get it started.
