The keys themselves were just metal with grooves that corresponded to the internal parts of the ignition cylinder. As technology improved the number of car makers began to mix electronic and physical protocols in order to prevent theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to start the vehicle.

The key chips contain an unique serial number which transmits a signal to the receiver inside your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes are compatible, then your car will start. If the codes don't match, your vehicle won't start at all. This is why you should keep an extra car key, especially if your system is transponder-based.

The chip absorbs the energy and then transmits reprogramming a car key radio frequency signal which contains an identification number. This code matches the unique serial numbers of the computer of the car. This helps prevent unauthorized attempts to start the car keys programmed since only the right key can do so.

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