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

If the codes are compatible, then your car will start. If the codes don't match, your vehicle won't start at all.
