Keys were made from metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. As time went on and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and they're designed to make it more difficult for thieves to start the vehicle.
The key chips come with an unique serial number which transmits a signal to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are identical the car will begin to begin to start. If the codes aren't compatible, your car will not even start. This is one of the primary reasons to keep a spare key in your vehicle, especially if you have a transponder-based system.

Most modern cars are equipped with the keyless entry system. This system works by emitting radio signals that are picked up using the keyfob. These signals are then compared against the correct code in the car's system, and when everything is in order, the car will unlock. The car will not start when the signals aren't the same. There are several ways to program your new key fob, if it isn't already programmed.

This stops unauthorized attempts to begin the car as only the correct keys will be able.
It is believed that this technology will 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.
