As technology advanced, more and more car makers began to mix electronic and physical protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it harder for thieves to steal a vehicle.
The key chips that are in the keys have a specific serial number that transmits signals to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are similar the car will begin to begin to start. If not, it won't start at all. This is the reason you should keep a spare car key, especially if the system is transponder-based.
You'll need special equipment to be able to program keys. You'll need to buy a blank key that is compatible with the car's model and make. They can be purchased from an auto dealership or from locksmiths however, you must be sure they're the right ones. If you try to use a key that is from an alternative model, it won't work.

The system can also detect and block stolen or lost cards. 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 car emits radio signals that are detected by a particular key fob. The signals are then compared with the correct code that is stored in the car's computer and if everything is in order the car will start to unlock. The car will not start in the event that the signals are not identical. There are a variety of steps you can follow to program your new key fob, if it's not already programmed.

Transponder Keys
Transponder keys are also known as chip keys. They are equipped with a microchip embedded inside the head of the keys.

The chip absorbs this energy, and then transmits a radio frequency signal that includes an identification code. The code is matched to the unique serial numbers that are stored in the computer system of the car. This stops any attempts by anyone else to start the car, as only proper keys will be able to do so.
This technology is thought to be more secure than a traditional car key because it makes it difficult for a thief "hot wire" the vehicle and start it. It's not foolproof, and thieves have found ways to trick and defeat the system. Therefore, even vehicles with a transponder key are not safe from theft.

Key fobs are equipped with electronic chips inside them that communicate with the car's receiver via radio signals. The computer in the car then compares the key's code to the one in its database. If the codes are the same, the car will start. If not, the car will be dead or refuses to start.
