Key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to start the vehicle.

When the signal is received it compares it with the code that is stored in the car's computer. If the codes are similar then your car will begin to start. If the codes aren't compatible, your car will not even start. This is one of the primary reasons to keep a spare key for your vehicle, particularly when you use a transponder-based system.
