As technology advanced the number of car manufacturers began to combine electronic and physical protocols to avoid theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.

The key chips inside the keys have a unique serial number, which transmits a signal to the receiver in your car. The signal is compared with a code in the computer of the car when it is received. If the codes are identical, your car will begin. If not, it won't start at all. This is why it is important to keep an extra car key, especially if your system is based on transponders.

This is to prevent any attempts by anyone else to start the car since only proper keys will be able to do so.

It is believed that this technology will be more secure than traditional car keys because it makes it harder for a thief to "hot wire" an automobile and start it.
