How to program a Key
Before the turn of the 21st century the majority of cars had basic key systems. Keys were made of metal and featured grooves that correspond to the internal parts in the ignition cylinder. However, as time progressed and technology improved, more and more car manufacturers began blending electronic and physical protocols to stop theft. These key systems, also known as transponder keys or chips keys are designed to make it harder for thieves to start the vehicle.
The key chips have unique serial codes which transmits a signal to the receiver in your car. The signal is compared to an identifier in the car's computer when it is received. If the codes match, your car will begin to start. If the codes aren't compatible, your car won't even start. This is one of the primary reasons you should keep a spare key for your vehicle, especially in the case of an electronic transponder.
If you want to learn how to program keys, you'll need some special equipment. You'll need to buy a blank key that is compatible with the car's model and make.

The latest models also support remote management and configuration and are cloud-based.
Modern cars are equipped with keyless entry systems. The system works by emitting radio signals that are detected by a special keyfob. These signals are then compared against the correct code that is stored in the car's computer and if everything is in order the car will start to unlock.

This will prevent any unauthorised attempts to start the car as only the correct key will be able to start the car.
This type of technology is thought to be more secure than a traditional car key, as it makes it harder for thieves to "hot wire" the vehicle and then start it.
