How to program a Key
The majority of cars had basic key systems up until the turn of 21st century. The keys themselves were metal and featured grooves that corresponded to the internal components of the ignition cylinder. As technology advanced, more and more car makers began to combine physical and electronic protocols in order to prevent 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 get into the vehicle.
The key chips inside the keys have a specific serial number, which transmits a signal to the receiver inside of your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are identical the car will begin to start. If not, it won't start at all. This is why it is important to keep an extra car key particularly if your system is based on transponders.
If you're looking to learn how to program keys, you'll require some specific equipment. You'll also require an uncut key for your particular make and model.

Additionally, the most recent models are cloud-based, allowing for remote management and configuration.
Most modern cars are equipped with the keyless entry system. This system works by emitting radio signals that are picked up using an specialized keyfob. The signals are then compared to the correct code that is stored in the car's computer and if everything is in order the car will start to unlock. The car will not start when the signals aren't the same. If your key fob is not already programmed, you may follow a series of steps to programme it.

This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that is matched with the unique digital serial number of the car's computer system. This is to prevent unauthorised attempts to start the car, as only correct keys will be able.
The technology is believed to be more secure than conventional car keys because it makes it much harder for a thief to "hot wire" an automobile and start it. It's not foolproof and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder key are not immune to theft.
