The keys themselves were just metal and featured grooves that corresponded to the internal parts of the ignition cylinder. As technology advanced, more and more automobile makers began to combine electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it difficult for thieves to get into the vehicle.
The key chips in the keys have a unique serial number that transmits an electronic signal to the receiver inside of your car. The signal is then compared to a code in the computer of the car when it is received. If the codes are compatible, then the car will start. If not, it will not start at all. This is one of the primary reasons to keep a spare key on your vehicle, particularly when you use transponder-based systems.
You'll require special equipment to be able to program keys. You'll need a blank key that is compatible with your car model and make. You can buy them at a locksmith or a car dealership, but it's crucial to get the right ones. If you use a key that is for another model, it won't function.

This prevents unauthorized attempts to start the car, as only the correct key will be able to perform the task.
The technology is believed to be more secure than a conventional car key since it makes it harder for thieves to "hot wire" the vehicle and start it.
