The majority of cars had basic keys systems until the turn of the 21st century. Keys themselves were metal and featured grooves that were connected to the internal parts of the ignition cylinder. As technology advanced, more and more automobile makers began to mix electronic and physical protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.

The key chips have an unique serial number which transmits a signal to the receiver in your car. The signal is compared with an identifier in the car's computer when it is received. If the codes are identical, your car will begin. If the codes aren't compatible, your vehicle won't start at all. This is the reason you should keep an extra car key especially if your system is based on transponders.

Most modern cars are equipped with the keyless entry system. To make this work the car emits radio signals that are detected by a particular key fob.

This helps prevent unauthorized attempts to start the car as only the correct key can do so.

This technology is thought to be more secure than a conventional car key since it makes it difficult for a criminal to "hot wire" the vehicle to start it.
