Self-Programming
In the lead-up to the 21st century, car keys technology started to move away from mechanical keys, and towards the use of a combination of physical and electronic protocols to prevent theft.

Professional locksmiths equipped with the required equipment can reprogram your keys. Many vehicles, especially luxury cars, require that only the dealer is allowed to make new keys.
If you're looking to attempt this yourself, the method differs by manufacturer. It generally involves inserting the spare key for the working car into the ignition, and manipulating it (in accordance with the instructions in your owner's manual) until your car is in programming mode. You'll need to move fast because this will only last a few seconds before your car is out of the mode.
Once your vehicle is in programming mode, you'll have to repeat the procedure for each key you want to program. The instructions in the owner's manual must be specific to the type of key and model you are trying to program, since some models have additional security features that need to be enabled (for instance a passcode required to access certain programming modes).
Some models of vehicles also require an additional code that must be obtained through the dealership at a cost to you. This code helps protect against "skimming", which is when thieves attempt to read your key's information through the OBD2 port in order to start the car and then steal it.

The key fob communicates to the receiver in the vehicle using radio signals. When you press the button on the keyfob, it transmits the code to the receiver, which performs the desired function. Key fobs are also a favorite among commercial building owners, who can integrate them into a larger access control system. This lets them track who enters or leaves and they can block fobs which have been stolen or lost.
