The majority of cars had basic key systems prior to the turn of the 21st century. Keys were made of metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. However, as time progressed and technology advanced, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to start the vehicle.
The key chips that are in the keys have a unique serial number that sends signals to the receiver inside of your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are similar, your car will begin to start. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key on your car, especially in the case of an electronic transponder.

In addition, the newest models are cloud-based and allow for remote management and configuration.
The majority of modern cars are equipped with the keyless entry system. The system works by sending radio signals that are picked up using the keyfob. The signals are then compared to the code that is stored in the car's computer, and if all is in order, the car will unlock. The car won't start when the signals aren't the same. There are a variety of steps you can take to program your new key fob, if it's not programmed yet.

This energy is absorbed into the chip and it transmits a radio frequency signal with an identification code that corresponds with the unique serial number that is stored in the car's computer system. This prevents unauthorised attempts to start the car since only right keys can be used.
This type of technology is thought to be more secure than a conventional car key because it makes it harder for a criminal to "hot wire" the vehicle to start it.
