As technology improved the number of car makers began to mix physical and electronic protocols to avoid theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it harder for thieves to get into the vehicle.

If the codes are compatible, then the car will start. If the codes aren't compatible, your car will not even start.
