How do you program a key
The majority of cars had basic keys systems until the turn of 21st century. Keys were made of metal and incorporated grooves to match the internal components in the ignition cylinder. As time went on and technology advanced as it did, automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it harder for thieves to get into the vehicle.
The key chips that are in the keys have a specific serial number that sends an electronic signal to the receiver inside of your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are compatible, then the car will start. If not, it will not start at all. This is one of the primary reasons you should keep a spare key in your car, especially if you have transponder-based systems.
You'll need special equipment to learn how to program keys. You'll need a blank key that is compatible with the car's model and make. You can buy them at an auto locksmith or a locksmith dealership, but it's crucial to buy the right one. If you use a key from another model, it won't work.
Begin by putting the new key in the ignition and turning it "on". You'll need to leave the key in this position for approximately 10 minutes and 30 seconds. Once the time has expired you can take out your key and verify that the security indicator on your dashboard has gone off. If not then you'll need to do it again for another time.

The newest models also allow remote management and configuration and are cloud-based.
Modern cars come with keyless entry systems. The system works by sending radio signals which are picked up using the keyfob. The signals are then compared to the code stored in the car's computer and, if all is well, the car will unlock. If the signals do not match, the car will not start. If your key fob is not already programmed, it is possible to follow a series of steps to programme it.

The antenna ring transmits electromagnetic energy to the transponder whenever the key is inserted into the ignition lock barrel. The chip absorbs this energy and then transmits a radio frequency signal that contains an identification code. The code is matched to the unique digital serial numbers that are stored in the computer of the car. This is to prevent unauthorised attempts to start the car since only right keys can be used.
It is believed that this technology will be more secure than traditional car keys because it makes it much difficult for thieves to "hot wire" a vehicle and start it. But it's not foolproof and thieves have found ways to deceive and thwart the system so that even cars with transponder keys are not safe from theft.
