As technology improved the number of car makers began to combine electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to get into the vehicle.

The key chips inside the keys have a specific serial number that sends a signal to the receiver inside of your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are compatible, then the car will start. If the codes aren't compatible, your car won't even start. This is why it is important to keep a spare car key, especially if the system is based on transponders.
