How to Program a Key
Most cars had basic key systems prior to the turn of 21st century. The keys themselves were just metal and featured grooves that corresponded to the internal parts of the ignition cylinder. As technology improved, more and more car makers began to combine physical and electronic protocols to stop theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it harder for thieves to open an automobile.
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 are compatible, then the car will start. If the codes don't match, then your car will not even start. This is why you should keep a spare car key, especially if your system is based on transponders.
You'll require special equipment to be able to program keys. You'll also need an uncut key for your specific make and model. They can be bought at a dealership or by locksmiths, but you must make sure that they are the correct ones. If you use a key that is for another model, it won't work.
To begin the process, insert the new key into the ignition and turn it to the "on" position. You'll need to keep the new key in this position for around 10 minutes and 30 seconds.

The system can also identify and disable stolen or lost cards. In addition, the latest models are cloud-based and permit remote management and configuration.
Most modern cars come equipped with an entry system that is keyless. This system works by emitting radio signals which are detected by the keyfob. These signals are then compared with the correct code stored in the car's computer and if everything is in order the car will be able to unlock. If the signals do not match and the car does not start. There are a variety of ways to program your new key fob, if it isn't already programmed.

It is possible to be instructed to insert the new key in the ignition after closing all doors, and then press the button on the keyfob after the time frame.

The antenna ring transmits electromagnetic energy to the transponder when the key is put into the barrel of the ignition lock. The chip absorbs this energy, and then sends a radio frequency signal that contains an identification code. This code is in line with the unique digital serial numbers that are stored in the computer of the car. This prevents unauthorised attempts to start the car since only right keys can be used.
This technology is thought to be more secure than a conventional car key because it makes it difficult for a thief "hot wire" the vehicle and then start it. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder keys aren't immune to theft.
