The keys themselves were metal and featured grooves that were connected to the internal components of the ignition cylinder. As technology advanced the number of car makers began to combine physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to start the vehicle.

If the codes are compatible, then your car will begin to start. If the codes don't match, your car will not even start.
