How do you program a key
Prior to the beginning of the 21st century most cars used basic key systems. The keys were made of metal and had grooves to correspond with the internal parts of the ignition cylinder. However, as time progressed and technology advanced, more and more automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to start the vehicle.
The key chips have unique serial codes that sends a message to the receiver inside your car. The signal is compared to the computer of the car when it is received. If the codes are similar, your car will begin. If not, it will not start at all. This is one of the primary reasons you should keep a spare key in your vehicle, especially if you have an electronic transponder.

Modern cars come with keyless entry systems. This system works by emitting radio signals that are picked up using the keyfob. The signals are compared with the code stored in the computer of the car and, if all is well, the car will unlock. If the signals don't match then the car won't start. If your key fob is not already programmed, you may follow a few steps to program it.

This energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched with the unique digital serial number of the car's computer system. This helps prevent an unauthorized attempt to start the car as only the correct key can perform the task.
This type of technology is thought to be more secure than a traditional car key since it makes it harder for a thief "hot wire" the vehicle and then start it. It's not foolproof and thieves have found ways to trick and defeat the system. Therefore, even vehicles with a transponder keys aren't safe from theft.
