How do you program a key
Most cars had basic key systems up until the turn of the 21st century. Keys were made of metal and incorporated grooves to correspond to the internal parts of the ignition cylinder. However, as time progressed and technology advanced as it did, car manufacturers began blending electronic and physical protocols to prevent theft. Key systems are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to steal an automobile.
The key chips in the keys have a specific serial number that transmits signals to the receiver in your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes are compatible, then your car will start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key in your car, especially when you use an electronic transponder.
You'll need special equipment to be able to program keys. You'll need an uncut key that matches the model and make of your car. They can be bought at an auto dealership or from a locksmith but you must make sure they're the right ones. If you use a key that is for another model, it won't work.

The newest models also allow remote management and configuration as well as are cloud-based.
Most modern cars come equipped with an entry system that is keyless. To make this work, the vehicle emits radio signals that are detected by a special key fob.

This stops any attempts by anyone else to start the car as only the proper keys will be able to do so.
