How to Program a Key
The majority of cars had basic key systems up until the turn of 21st century. The keys themselves were just metal and featured grooves that were connected to the internal parts of the ignition cylinder. As technology improved, more and more car makers began to combine electronic and physical protocols in order to prevent theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open the vehicle.
The key chips contain an unique serial number which transmits a signal to the receiver inside your car. The signal is then compared to a code in the car's computer when it is received. If the codes are identical then your car will start. If the codes aren't compatible, your car will not even start. This is one of the primary reasons to keep a spare key in your vehicle, especially if you have an electronic transponder.
If you're looking to learn how to program keys, you'll need certain equipment. You'll also require a blank key for your specific make and model.

Keyless Entry Systems
Keyless entry systems allow access to your property without the need for a physical credential. They use a combination of sensors and an onboard computer to offer security. It is possible to manage and monitor the system from anywhere within the property. Keys and locks are not required. The system is also able to detect and disable stolen or lost cards. The latest models also support remote management and configuration as well as are cloud-based.
The majority of modern cars are equipped with an entry system that is keyless. The system works by sending radio signals that are detected by the keyfob. The signals are compared with the code that is stored in the computer of the car, and if all is well the car will be able to unlock. If the signals do not match and the car does not start. If your key fob isn't already programmed, you can follow a series of steps to program it.
First, you'll need to ensure all the doors are locked, except for the driver's side. You'll need to have the original key fob along with any additional devices you want to program.

Transponder Keys
Transponder keys are also referred to as chip key. They are equipped with a microchip embedded in the head of the keys. When the key is placed in the barrel of the ignition lock, and then turned to the ON position, the antenna ring sends an electromagnetic energy blast through the transponder chip. The energy is absorbed by the chip and sends back the radio frequency signal, which includes an identification code that corresponds with the unique serial number that is stored in the car's computer system. This will prevent any unauthorised attempts to start the car because only a valid key can do so.
This type of technology is thought to be more secure than the traditional car key since it makes it difficult for a criminal to "hot wire" the vehicle to 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 safe from theft.
You might be able to program a transponder key by yourself if you have an appropriate key programmer for your car. The key programmer comes with a guide that will guide you step-by-step through the procedure. Follow the steps and turn on the security light on your dashboard before you start your engine.

This will save you money and time, and keep your car's safety system operating exactly as it should. It is also safer than doing it yourself. If you use the incorrect key programming software or follow a guide that is not official or instructions, the information stored in your car's system could be damaged and the new key won't function.

The key fobs have electronic chips that communicate with the car's receiver using radio signals. The car's computer then compares the code on the key to the one in its database. If the codes match the car starts. If the codes do not match the car won't start or remain dead. Luckily, most of these electronic keys can be programmed and replaced by an expert locksmith or an auto dealer using the appropriate equipment.
