How to program a Key
Prior to the beginning of the 21st century, the majority of cars utilized basic key systems. Keys were made of metal and had grooves to match the internal components of the ignition cylinder. As technology advanced, more and more car makers began to combine electronic and physical protocols to stop theft. Key systems are also referred to as transponder keys or chips keys, are designed to make it difficult for thieves to open a vehicle.
The key chips inside the keys have a specific serial number, which transmits signals to the receiver in your car. The signal is compared with the computer of the car when it is received. If the codes match, the car will start. If not, it will not start at all. This is why it is important to keep an extra car key especially if the system is based on transponders.
You'll require special equipment to learn how to program keys. You'll also require the blank key that matches your specific model and make. You can buy them at the locksmith shop or at a car dealership, but it's essential to buy the right one. If you attempt to use a key that is from another model, then it won't work.

This system works by emitting radio signals which are received by the keyfob. programing keys are then compared with the correct code that is stored in the car's computer, and when everything is in order the car will be able to unlock. The car will not start when the signals aren't identical. If your key fob is not already programmed, it is possible to follow several steps to program it.

This energy is absorbed by the chip and sends back a radio frequency signal with an identification code that is matched with the unique serial number that is stored in the car's computer system. This prevents unauthorised attempts to start the car as only the proper keys will be able to do so.
It is believed that this technology will be more secure than traditional car keys because it makes it harder for a thief to "hot wire" a vehicle and start it.
