How to program a key
Up until the turn of the 21st century the majority of cars utilized basic key systems. Keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. As technology advanced, more and more car manufacturers began to combine electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it more difficult for thieves to start the vehicle.
The key chips in the keys have a unique serial number that sends a signal to the receiver inside of your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match then your car will start. If not, it won't start at all. This is one of the main reasons to keep a spare key for your car, especially when you use a transponder-based system.
If you're interested in learning how to program keys, you'll require some special equipment. You'll also need the blank key that matches your specific make and model. You can buy them at a locksmith or a car dealership, but it's important to purchase the correct keys. If you use a key that is for another model, it won't work.

This technology is thought to be more secure than a traditional car key since it makes it more difficult for a thief "hot wire" the vehicle to start it.
