As technology improved the number of car manufacturers began to combine physical and electronic protocols to avoid theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.
The key chips contain a unique serial code which transmits a signal to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical then your car will begin. If not, it will not start at all. This is one of the main reasons you should keep a spare key for your car, especially in the case of a transponder-based system.

Most modern cars come equipped with a keyless entry system. To enable this feature the car emits radio signals which are picked up by a particular key fob. The signals are then compared to the code stored in the car's computer, and if all is in order the car will start to unlock. The car won't start in the event that the signals are not identical. There are several ways to program your new key fob, if it's not already programmed.

This prevents unauthorised attempts to start the car since only the right key will be able to perform the task.
It is believed that this technology will be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" a vehicle and start it.
