How to Program a Key
Up until the turn of the 21st century, the majority of cars had basic key systems. Keys themselves were metal and featured grooves that were connected to the internal parts of the ignition cylinder. As time passed and technology improved as it did, automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to open an automobile.
The key chips come with unique serial codes which transmits a signal to the receiver inside your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes match, your car will begin. If not, it will not start at all. This is why it is important to keep an extra car key, particularly if your system is transponder-based.
You'll require specialized equipment to learn how to program keys. You'll need to buy a blank key that is compatible with the car's model and make. These can be purchased at an auto dealership or from a locksmith, but you must make sure that they are the correct ones. If you attempt to use a key that is from an alternative model, it will not work.

Modern cars come with keyless entry systems. The system works by sending radio signals which are picked up using an specialized keyfob. The signals are compared with the code that is stored in the car's computer and, if all is in order the car will start to unlock. The car won't start if the signals are not the same. If your key fob is not already programmed, you can follow a series of steps to program it.

The energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that is matched up to the unique serial number that is stored in the car's computer system. This stops unauthorised attempts to start the car as only the proper keys will be able to do so.
This technology is thought to be more secure than a traditional car key since it makes it more difficult for thieves to "hot wire" the vehicle and then start it.
