Before the turn of the 21st century, the majority of cars utilized basic key systems. Keys themselves were metal and had grooves that were connected to the internal parts of the ignition cylinder. As time passed and technology advanced, more and more car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.

The key chips inside the keys have a specific serial number, which transmits a signal to the receiver inside of your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are similar, your car will begin. If not, it won't start at all. This is one of the primary reasons to keep a spare key on your vehicle, especially if you have an electronic transponder.

This is to prevent unauthorised attempts to start the car since only proper keys will be able to do so.

This type of technology is thought to be more secure than the traditional car key since it makes it more difficult for thieves to "hot wire" the vehicle and start it.
