How do you program a key?
Prior to the beginning of the 21st century the majority of cars had basic key systems. The 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, car manufacturers began blending physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to get into the vehicle.
The key chips contain a unique serial code 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, your car will begin. If the codes don't match, then your car will not even start. This is the reason you should keep an extra car key especially if the system is based on transponders.
If you're looking to learn how to program keys, you'll require some specific equipment. You'll also need to purchase a blank key that matches your specific model and make. They can be purchased from an auto dealership or from a locksmith, but you must make sure that they are the right ones. If you attempt to use a key that is from another brand, it won't work.

This prevents an unauthorized attempt to start the car, because only a valid key can perform the task.
This technology is thought to be more secure than a conventional car key, as it makes it difficult for a criminal to "hot wire" the vehicle and then start it.
