As time went on and technology improved and improved, car manufacturers began blending electronic and physical protocols to prevent theft. Key systems like these are also referred to as transponder keys or chips keys, are designed to make it harder for thieves to steal an automobile.

The key chips come with unique serial codes that transmits a message to the receiver inside your car. The signal is compared to a code in the computer of the car when it is received. If the codes are identical then your car will begin. If not, it won't start at all. This is one of the primary reasons to keep a spare key for your car, especially when you use transponder-based systems.

Additionally, the most recent models are cloud-based and allow for remote management and configuration.

Most modern cars are equipped with an entry system that is keyless. The system works by sending radio signals that are detected by a special keyfob. The signals are then compared to the code stored in the car's computer, and if all is well, the car keys programming will unlock. If the signals do not match, the car will not start.

This code matches the unique digital serial numbers that are stored in the computer of the car. This prevents unauthorized attempts to start the car since only the right key will be able to start the car.

It is believed that this technology will be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" an automobile and start it.
