However, as time progressed and technology advanced, more and more automobile manufacturers began blending electronic and physical protocols to prevent theft. Key systems also known as transponder keys or chips keys, are designed to make it difficult for thieves to open a vehicle.

If the codes are compatible, then the car will start. If the codes aren't compatible, your car will not even start. This is why it is important to keep an extra car key, especially if the system is based on transponders.
