Most cars had basic key systems until the turn of the 21st century. Keys were made of metal and had grooves to correspond with the internal parts in the ignition cylinder. However, as time progressed and technology advanced and improved, automobile manufacturers began blending electronic and physical protocols to protect against theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to start the vehicle.

The signal is compared with an identifier in the computer of the car when it is received. If the codes match, then your car will start. If the codes don't match, then your vehicle won't start at all. This is why you should keep an extra car key particularly if your system is transponder-based.
