The keys themselves were just metal with grooves that matched the internal components of the ignition cylinder. As technology advanced, more and more car makers began to mix electronic and physical protocols in order to prevent theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.
The key chips contain unique serial codes that sends a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are identical, your car will start. If the codes don't match, then your vehicle won't start at all. This is the reason you should keep an extra car key, especially if your system is transponder-based.

The chip absorbs the energy and then sends a radio frequency signal that includes an identification code. This code is in line with the unique digital serial numbers of the car's computers. This is to prevent unauthorised attempts to start the car, as only right keys can be used.
The technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" a vehicle and get it started.
