As technology improved the number of car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips come with an unique serial number that sends a message to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer.

The latest models also support remote management and configuration, and are cloud-based.
Modern cars are equipped with keyless entry systems. To enable this feature, the vehicle emits radio signals which are picked up by a specific key fob. The signals are then compared with the correct code stored in the car's computer, and if everything is in order the car will be able to unlock. The car won't start in the event that the signals are not the same. If your key fob has not been already programmed, you may follow a series of steps to programme it.

The chip absorbs this energy and then sends a radio frequency signal which contains an identification number. This code is in line with the unique digital serial numbers in the computer system of the car. This helps prevent unauthorised attempts to start the car as only the correct key will be able to start the car.
This technology is believed to be more secure than conventional car keys because it makes it more difficult for thieves to "hot wire" an automobile and start it. It's not foolproof and thieves have discovered ways to trick and defeat the system. Therefore, even vehicles with a transponder keys aren't protected from theft.

The key fobs contain electronic chips that communicate via radio signals to the car's receiver. The car's computer then compares the code on the key to the one stored in its database. If the codes match, the car will start. If not, the vehicle will remain dead or refuse to start. Fortunately, the majority of electronic keys can be replaced and programmed by an expert locksmith or an auto dealer with the right equipment.
