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 to the internal parts in the ignition cylinder. As technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to get into the vehicle.
The key chips come with an unique serial number that sends a message to the receiver in your car. The signal is compared with a code in the car's computer when it is received. If the codes are similar the car will begin to begin. If the codes aren't compatible, your car will not even start. This is one of the primary reasons you should keep a spare key in your vehicle, especially if you have an electronic transponder.
You'll need special equipment to learn how to program keys. You'll also need to purchase the blank key that matches your specific model and make.
