As time passed and technology advanced and improved, automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys and they're designed to make it more difficult for thieves to open the vehicle.

The key chips have a unique serial code that sends a message to the receiver in your car. The signal is compared to a code in the car's computer when it is received. If the codes match, then your car will begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key in your vehicle, especially if you have a transponder-based system.

The chip absorbs the energy and then sends a radio frequency signal which contains an identification number. The code is matched to the unique serial numbers of the computer of the car. This helps prevent unauthorised attempts to start the car, because only a valid key can start the car.
