Most cars had basic key systems until the turn of 21st century. The keys were made of metal and had grooves to correspond to the internal parts in the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to stop theft. Key systems are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to open a vehicle.
The key chips that are in the keys have a unique serial number, which transmits an electronic signal to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match, your car will begin to start. If not, it won't start at all. This is why it is important to keep an extra car key, especially if the system is based on transponders.

The signals are then compared to the correct code that is stored in the car's computer and if everything is in order the car will be able to unlock. The car will not start when the signals aren't the same. If your key fob is not already programmed, you can follow several steps to programme it.

This helps prevent unauthorised attempts to start the car, as only the correct key can perform the task.
This technology is thought to be more secure than the traditional car key because it makes it harder for thieves to "hot wire" the vehicle and then start it.
