The keys themselves were metal and featured grooves that corresponded to the internal components of the ignition cylinder. As time passed and technology advanced as it did, car manufacturers began blending physical and electronic protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.

The key chips inside the keys have a specific 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 are compatible, then the car will start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep an extra car key particularly if your system is transponder-based.

You'll require special equipment to be able to program keys. You'll also need to purchase the blank key for your particular make and model. You can purchase these at an auto locksmith or a locksmith dealership, but it's important to get the right ones. If you attempt to use a key that is from another brand, it will not work.

This is to prevent unauthorised attempts to start the car as only the correct keys will be able.
