As time passed and technology advanced as it did, car manufacturers began blending physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys, and they're designed to make it difficult for thieves to get into the vehicle.

The key chips in the keys have a unique serial number, which transmits signals to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, your car will begin to start. If the codes don't match, then your vehicle won't start at all. This is the reason you should keep an extra car key especially if the system is transponder-based.

This code is in line with the unique digital serial numbers that are stored in the car's computers. This will prevent any unauthorised attempts to start the car since only the right key can perform the task.

This type of technology is thought to be more secure than a traditional car key, as it makes it harder for a criminal to "hot wire" the vehicle and then start it.
