How to Program a Key
The majority of cars had basic key systems until the turn of 21st century. The keys themselves were metal and had grooves that matched the internal parts of the ignition cylinder. As time went on and technology improved as it did, automobile manufacturers began to combine electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.
The key chips in the keys have a unique serial number that sends a signal to the receiver inside your car. The signal is compared with the car's computer when it is received. If the codes are identical the car will begin to begin to start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key on your vehicle, particularly when you use transponder-based systems.
You'll require special equipment to be able to program keys. You'll need to buy an uncut key that matches the model and make of your car.

Modern cars are equipped with keyless entry systems. To enable this feature it emits radio signals that are detected by a particular key fob. These signals 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 antenna ring transmits electromagnetic energy to the transponder whenever the key is placed in the barrel of the ignition lock. The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches with the unique digital serial number of the car's computer system. This prevents an unauthorized attempt to start the car, since only the right key can do so.
The technology is believed to be more secure than conventional car keys because it makes it much difficult for thieves to "hot wire" an automobile and start it. It's not foolproof, and thieves have found ways to evade detection and defeat the system. So even mobile car key programmer with transponder keys aren't safe from theft.
