Before the turn of the 21st century the majority of cars utilized basic key systems. The keys were made of metal and incorporated grooves to correspond to the internal parts of the ignition cylinder. As technology improved the number of car makers began to combine electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to open the vehicle.
The key chips inside the keys have a unique serial number that transmits a signal to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match, the car will start. If the codes don't match, your vehicle won't start at all. This is one of the primary reasons why you should always keep a spare key on your car, especially in the case of an electronic transponder.

The code is matched to the unique serial numbers that are stored in the computer system of the car. This prevents any attempts by anyone else to start the car as only the proper keys will be able to do so.
The technology is believed to be more secure than the traditional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle and start it.
