As technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols in order to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it harder for thieves to get into the vehicle.

The key chips that are in the keys have a unique serial number that sends an electronic signal to the receiver inside of your car. The signal is compared to a code in the computer of the car when it is received. If the codes match, the car will start. If not, it won't start at all.

This is to prevent unauthorized attempts to begin the car since only proper keys will be able to do so.

This technology is believed to be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" an automobile and get it started.
