The keys themselves were just metal with grooves that were connected to the internal components of the ignition cylinder. As technology improved, more and more automobile makers began to combine electronic and physical protocols in order to prevent theft. Key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to start the vehicle.

The key chips in the keys have a specific serial number, which transmits an electronic signal to the receiver inside your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes match, your car will start. If the codes don't match, then your car will not even start.

The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. This code matches the unique serial numbers in the car's computers. This is to prevent any attempts by anyone else to start the car since only proper keys will be able to do so.

This type of technology is thought to be more secure than a conventional car key since it makes it harder for a thief "hot wire" the vehicle and start it.

If the codes match the car will begin. If the codes do not match the car won't start or remain dead. Luckily, most of these electronic keys can be programmed and replaced by an experienced locksmith or an auto dealer using the appropriate equipment.
