The majority of cars had basic key systems up until the turn of 21st century. Keys were made from metal and incorporated grooves to correspond with the internal parts in the ignition cylinder. As time passed and technology advanced, more and more automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it difficult for thieves to get into the vehicle.

The key chips come with an unique serial number that sends a message to the receiver in your car. The signal is compared to the car's computer when it is received. If the codes are compatible, then the car will start. If not, it won't start at all. This is one of the main reasons to keep a spare key in your vehicle, especially when you use transponder-based systems.

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

Modern cars come with keyless entry systems. To enable this feature the car emits radio signals that are detected by a special key fob. The signals are compared to the code stored in the car's computer, and if all is in order the car will start to unlock. The car won't start in the event that the signals are not the same. There are a variety of ways to program your new key fob, if it's not already programmed.

The chip absorbs this energy and then transmits a radio frequency signal that includes an identification code. This code matches the unique digital serial numbers that are stored in the computer 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 thought to be more secure than a conventional car key because it makes it difficult for a thief "hot wire" the vehicle to start it.
