It requires soldering skills, electronic knowledge and a lot time.
Other kinds of programming car keys are much easier and can be done by the average person.

Transponder Chips
If your car is made within the last 20 years, it is likely that it contains a transponder chip within of it. This is a little plastic piece on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip inside the key is the correct one for your specific vehicle.
This stops the vehicle from starting by hot-wiring or tampering. The chip inside the car key verifies that the owner is the person who owns the vehicle. This will help reduce the possibility of theft from your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be received by the chip and cause it to transmit a signal back to the car. If the onboard car computer recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and notify you via flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. mobile car key programming and skilled criminal could still bypass this system using a special device that blocks the signal.

When you press the button on your key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then opens or locks the car's doors. If the information does not match, the car will not be allowed to operate.
Once the car is paired with a particular fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they appear similar. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge that can only be found in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by customers without the need of dealers.
