How to program a Key
Before the turn of the 21st century, the majority of cars utilized basic key systems. Keys were made from metal and incorporated grooves to correspond with the internal parts in the ignition cylinder. As time went on and technology advanced as it did, car manufacturers began blending physical and electronic protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to open the vehicle.
The key chips contain unique serial codes that transmits a message to the receiver in your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are compatible, then the car will start. If the codes don't match, your vehicle won't start at all. This is one of the main reasons to keep a spare key in your car, especially if you have transponder-based systems.
You'll need special equipment to be able to program keys. You'll need to buy a blank key that is compatible with the model and make of your car. They can be purchased from the dealership or through a locksmith however, you must be sure they're the right ones. If you use a key for another model, it won't work.
Start the process by inserting the new key into the ignition and turning it "on". You'll need to leave the key in this position for around 10 minutes and 30 seconds. After the time is up you can take off your key and verify that the security indicator on your dashboard has gone out. If it didn't, you will need to do it a third time.

The most recent models also permit remote management and configuration as well as are cloud-based.
Modern cars are equipped with keyless entry systems. To enable this feature it emits radio signals that are detected by a particular key fob.

The antenna ring transmits electromagnetic energy to the transponder when the key is inserted in the barrel of the ignition lock. The chip absorbs this energy and then sends a radio frequency signal that contains an identification code. This code matches the unique serial numbers in the computer system of the car. This prevents unauthorised attempts to start the car since only proper keys will be able to do so.
It is believed that this technology will be more secure than conventional car keys because it makes it much more difficult for thieves to "hot wire" the vehicle and start it. It's not foolproof, and thieves have discovered ways to evade detection and defeat the system. Therefore, even vehicles with a transponder key are not protected from theft.
Depending on the brand and model of your car depending on the make and model of your car, you might be capable of programming a new transponder by yourself with a key programer that is compatible with your specific car.
