As time went on and technology advanced as it did, car manufacturers began blending electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.

The key chips that are in the keys have a specific serial number that sends signals to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes are compatible, then your car will begin to start. If not, it won't start at all.
