How do you program the key
Prior to the beginning of the 21st century, the majority of cars had basic key systems. Keys were made from metal and featured grooves that match the internal components of the ignition cylinder. As technology improved the number of car manufacturers began to combine electronic and physical protocols to stop theft. These key systems are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to open the vehicle.
The key chips in the keys have a specific serial number, which transmits signals to the receiver inside of your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are similar the car will begin to begin to start. If not, it won't start at all. This is the reason you should keep an extra car key particularly if your system is based on transponders.
You'll require specialized equipment to learn how to program keys. You'll need to buy an uncut key that matches the car's model and make. These can be purchased at the dealership or through a locksmith, but you must make sure that they are the correct ones. If you attempt to use a key from another model, then it will not work.

The latest models also support remote management and configuration as well as are cloud-based.
Modern cars are equipped with keyless entry systems. The system works by emitting radio signals that are picked up using an specialized keyfob. The signals are then compared to the code stored in the car's computer and if everything is well the car will start to unlock. The car won't start if the signals are not identical. There are several steps you can follow to program your new key fob if it's not already programmed.

This energy is absorbed into the chip and it transmits an audio frequency signal that contains an identification code that is matched with the unique digital serial number that is stored in the car's computer system. This will prevent any unauthorised attempts to start the car as only the correct key can do so.
This technology is thought to be more secure than a conventional car key since it makes it difficult for thieves to "hot wire" the vehicle and then start it. It's not foolproof and thieves have found ways to trick and defeat the system. So even cars equipped with transponder key are not immune to theft.
