Keys themselves were metal and had grooves that were connected to the internal parts of the ignition cylinder. As technology advanced the number of car makers began to mix electronic and physical protocols in order to prevent theft. Key systems, also known as transponder keys or chips keys are designed to make it difficult for thieves to steal an automobile.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver in 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. This is one of the main reasons why you should always keep a spare key for your car, especially in the case of an electronic transponder.

This prevents unauthorized attempts to begin the car as only the right keys can be used.
The technology is believed to be more secure than traditional keys for cars because it makes it much more difficult for thieves to "hot wire" an automobile and get it started.
