How to program a Key
The majority of cars had basic keys systems up until the turn of 21st century. The keys were made of metal and had grooves to match the internal components in the ignition cylinder. As technology advanced the number of car manufacturers began to combine electronic and physical protocols to avoid theft. These key systems are known 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 in the keys have a unique serial number, which transmits an electronic signal to the receiver in your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes are similar then your car will start. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep an extra car key, particularly if your system is transponder-based.
If you're interested in learning how to program keys, you'll require certain equipment. You'll need to buy a blank key that matches your car model and make. You can purchase these at an auto locksmith or a locksmith dealership, but it's important to get the right ones. If you try to use a key that is from an alternative model, it will not work.

The latest models also support remote management and configuration, and are cloud-based.
Modern cars come with keyless entry systems. To enable this feature it emits radio signals which are picked up by a special key fob. The signals are compared with the code stored in the car's computer and if everything is in order, the car will unlock. The car won't start when the signals aren't the same. There are several steps you can follow to program your new key fob, if it isn't already programmed.

This prevents unauthorized attempts to begin the car, as only right keys can be used.
The technology is believed to be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" a vehicle and start it. However, it's not foolproof and thieves have discovered ways to trick and defy the system - which means that even cars equipped that have transponder keys aren't protected from theft.
