How to program the key
The majority of cars had basic keys systems prior to the turn of the 21st century. The keys were made of metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As technology advanced the number of car makers began to combine electronic and physical protocols to stop theft. These key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal an automobile.
The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver inside of your car. When programming car key is received it compares it with a code stored in the car's computer. If the codes match then your car will begin. If the codes don't match, your vehicle won't start at all. This is why you should keep an extra car key, especially if the system is transponder-based.
You'll require specialized equipment to learn to program keys. You'll need an uncut key that matches the model and make of your car. They can be bought at the dealership or through locksmiths, but you must make sure they're the correct ones. If you use a key for another model, it won't function.

The system is also able to detect lost or stolen cards and disable them. In addition, the newest models are cloud-based and allow for remote management and configuration.
Modern cars come with keyless entry systems. To enable this feature, the vehicle emits radio signals which are picked up by a specific key fob. These signals are then compared with the correct code in the car's computer, and if everything is in order, the car will unlock. The car will not start when the signals aren't identical. There are a variety of steps you can follow to program your new key fob, if it isn't already programmed.

When the key is inserted into the barrel of the ignition lock and turned into the ON position the antenna ring transmits a burst of electromagnetic energy through the transponder chip. 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 in the computer of the car. This helps prevent unauthorized attempts to start the car as only the correct key can do so.
This type of technology is thought to be more secure than a traditional car key because it makes it more difficult for thieves to "hot wire" the vehicle and start it. But it's not foolproof and thieves have found ways to trick and defy the system - so that even vehicles with transponder keys aren't immune from theft.
You might be able to program a transponder key on your own if you have an appropriate key programmer for your vehicle. The key programmer should include a step-by-step guide that will walk you through the procedure of programming your key.
