The majority of cars had basic key systems prior to the turn of the 21st century. The keys were made of metal and incorporated grooves to match the internal components in the ignition cylinder. As technology advanced the number of car makers began to mix physical and electronic protocols to avoid theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to steal a vehicle.
The key chips contain a unique serial code that sends a message to the receiver in your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes match, then your car will begin to start. If not, it won't start at all. This is the reason you should keep an extra car key especially if your system is transponder-based.

The signals are then compared to the correct code stored in the car's computer and when 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 is not already programmed, you can follow a few steps to program it.

This helps prevent an unauthorized attempt to start the car as only the correct key can start the car.
This technology is thought to be more secure than a conventional car key because it makes it more difficult for thieves to "hot wire" the vehicle and then start it.
