How to program the key
Most cars had basic key systems up until the turn of 21st century. Keys were made of metal and featured grooves that match the internal components of the ignition cylinder. As time went on and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to protect against theft. Key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal the vehicle.
The key chips have unique serial codes that sends a message to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are similar the car will 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 in the case of an electronic transponder.
You'll require specialized equipment to learn how to program keys. You'll need a blank key that is compatible with the car's model and make.

In addition, the latest models are cloud-based, allowing for remote management and configuration.
Modern automobiles are equipped with keyless entry systems. To accomplish this the car emits radio signals which are picked up by a special key fob. These signals are then compared to the correct code that is stored in the car's computer and if everything is in order the car will start to unlock.

The chip absorbs the energy and then transmits a radio frequency signal that contains an identification code. This code is in line with the unique digital serial numbers of the computer of the car. This stops any attempts by anyone else to start the car, as only right keys can be used.
This type of technology is thought to be more secure than a conventional car key since it makes it more difficult for a criminal to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways to trick and defeat the system. So even cars equipped with transponder keys aren't safe from theft.
