As time passed and technology improved, more and more car manufacturers began blending electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.
The key chips contain a unique serial code that sends a message to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes are similar the car will begin to begin. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key on your car, especially if you have an electronic transponder.

This prevents unauthorized attempts to begin the car since only right keys can be used.
