How to program a key

The majority of cars had basic key systems up until the turn of the 21st century. The keys were made of metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As time went on and technology advanced and improved, 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 more difficult for thieves to steal a vehicle.

The key chips in the keys have a specific serial number that transmits an electronic signal to the receiver inside your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are identical, your car will begin. If not, it will not start at all. This is why it is important to keep an extra car key especially if your system is transponder-based.
