How to Program a Key
Most cars had basic key systems until the turn of 21st century. The keys themselves were just metal and featured grooves that matched the internal components of the ignition cylinder. However, as time progressed and technology improved, more and more car manufacturers began blending physical and electronic protocols to prevent theft. These key systems also known as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.
The key chips contain an unique serial number that transmits a message to the receiver inside your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are similar the car will begin to begin to start. If not, it will not start at all. This is one of the primary reasons to keep a spare key for your car, especially when you use an electronic transponder.

The chip absorbs this energy and then sends a radio frequency signal that contains an identification code. This code matches the unique digital serial numbers of the car's computers. This will prevent any unauthorised attempts to start the car, because only a valid key can start the car.
The technology is believed to be more secure than traditional car keys because it makes it more difficult for thieves to "hot wire" a vehicle and get it started.
