As technology improved, more and more automobile makers began to mix electronic and physical protocols in order to prevent theft. Key systems 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 that are in the keys have a unique serial number that sends a signal to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes match, your car will begin to start. If the codes aren't compatible, your car won't even start. This is why you should keep a spare car key, especially if your system is transponder-based.

This code is in line with the unique digital serial numbers of the computer system of the car. This prevents unauthorized attempts to begin the car, as only right keys can be used.

This technology is thought to be more secure than a conventional car key since it makes it harder for thieves to "hot wire" the vehicle to start it.
