As technology advanced the number of car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it difficult for thieves to start the vehicle.
The key chips contain an unique serial number that transmits a message to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match, the car will start. If not, it won't start at all. This is why it is important to keep an extra car key especially if your system is based on transponders.

This is to prevent any attempts by anyone else to start the car since only right keys can be used.
car key programmer of technology is thought to be more secure than a conventional car key, as it makes it harder for a thief "hot wire" the vehicle to start it.
