As technology improved, more and more automobile makers began to combine physical and electronic protocols in order to prevent theft. These key systems, also known as transponder key programming keys or chips keys are designed to make it difficult for thieves to start a vehicle.

The key chips come with an unique serial number that sends a message to the receiver inside your car. The signal is then compared to a code in the car's computer when it is received. If the codes match, then your car will begin to start. If not, it will not start at all.

This helps prevent unauthorised attempts to start the car, since only the right key can do so.

This technology is believed to be more secure than traditional car keys because it makes it difficult for thieves to "hot wire" the vehicle and get it started.
