As technology advanced, more and more automobile makers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.
The key chips have a unique serial code that transmits a message to the receiver inside your car. The signal is then compared to the computer of the car when it is received. If the codes are compatible, then your car will begin to start. If the codes don't match, then your car won't even start. This is why you should keep a spare car key, especially if the system is based on transponders.
