As time went on and technology advanced and improved, car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it harder for thieves to get into the vehicle.

The key chips inside the keys have a unique serial number that sends signals to the receiver in your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are compatible, then your car will start. If not, it will not start at all. This is the reason you should keep an extra car key, particularly if your system is based on transponders.

If you're looking to learn how to program keys, you'll require certain equipment. You'll also need to purchase the blank key for your particular model and make.

This is to prevent unauthorized attempts to begin the car as only the correct keys will be able.

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