How do you program a key?
Prior to the beginning of the 21st century most cars used basic key systems. The keys themselves were just metal and had grooves that matched the internal parts of the ignition cylinder. As technology improved the number of car makers began to mix physical and electronic protocols in order to prevent theft. Key systems are also referred to as transponder keys or chips keys are designed to make it harder for thieves to steal the vehicle.
The key chips inside the keys have a unique serial number that sends a signal to the receiver inside your car. The signal is compared to the car's computer when it is received. If the codes match, then your car will start. If the codes don't match, then your car won't even start. This is why you should keep an extra car key especially if the system is transponder-based.
You'll require specialized equipment to be able to program keys. You'll also require an uncut key for your particular make and model. They can be purchased from a dealership or by a locksmith but you must make sure they're the right ones. If you attempt to use a key from another brand, it will not work.

Additionally, the most recent models are cloud-based and allow for remote management and configuration.
Modern cars come with keyless entry systems. This system works by emitting radio signals which are picked up using the keyfob. The signals are then compared to the correct code in the car's system, and when everything is in order the car will be able to unlock. The car will not start if the signals are not identical. If your key fob is not already programmed, you can follow a series of steps to program it.

This energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that corresponds up to the unique serial number of the car's computer system. This stops unauthorised attempts to start the car, as only correct keys will be able.
This technology is believed to be more secure than conventional car keys because it makes it harder for a thief to "hot wire" an automobile and get it started. 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.

This will save you money and time, and keep your car's safety system working just as it should. Plus, it's a lot more secure than doing it yourself!
