As technology advanced, more and more automobile makers began to combine electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to open the vehicle.
The key chips that are in the keys have a unique serial number, which transmits signals to the receiver inside of your car. The signal is compared with an identifier in the car's computer 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 main reasons why you should always keep a spare key for your car, especially when you use a transponder-based system.

Modern automobiles are equipped with keyless entry systems. To make this work, the vehicle emits radio signals which are picked up by a specific key fob. These signals are then compared with the correct code in the car's system, and if everything is in order the car will start to unlock. The car won't start when the signals aren't identical. If your key fob isn't already programmed, you can follow a few steps to program it.

The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. The code is matched to the unique digital serial numbers in the computer of the car. This helps prevent an unauthorized attempt to start the car since only the right key will be able to start the car.
The technology is believed to be more secure than conventional car keys because it makes it harder for a thief to "hot wire" a vehicle and get it started. It's not foolproof and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder key are not protected from theft.

Key fobs are equipped with electronic chips which communicate with the car's receiver using radio signals. The car's computer then compares this key's code with the one stored in its database. If the codes are the same the car will be able to start. If not, the car will not start or fail to start.
