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 come with a unique serial code that sends a message to the receiver inside your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes match then your car will start. If not, it won't start at all. This is one of the main reasons to keep a spare key on your car, especially if you have a transponder-based system.

This prevents any attempts by anyone else to start the car, as only proper keys will be able to do so.

The technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" the vehicle and get it started.
