How do you program a key?
The majority of cars had basic keys systems up until the turn of the 21st century. The keys were made of metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As time passed and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to stop theft. Key systems, also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open the vehicle.
The key chips contain an unique serial number that transmits a message to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes are compatible, then your car will start. If the codes don't match, your car won't even start. This is one of the main reasons why you should always keep a spare key in your car, especially if you have a transponder-based system.
If you're looking to learn how to program a key, you'll need certain equipment. You'll also need an uncut key that matches your specific make and model.

This energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that matches with the unique serial number that is stored in the car's computer system. This is to prevent unauthorised attempts to start the car as only the right keys can be used.
This type of technology is thought to be more secure than a traditional car key because it makes it harder for a thief "hot wire" the vehicle to start it.
