It requires soldering skills, electronic knowledge and a lot time.

Transponder Chips
If your car was manufactured in the last 20 years, it is likely that it has a transponder inside of it. It's a small plastic piece inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip inside the key ensures that the owner is the one who owns the vehicle. This helps to prevent car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is housed in the plastic portion of the key, and there are different types of cuts on the keys: a standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer in the car is able to recognize the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will alert you with flashing lights and siren. This is designed to discourage people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined thief might be able bypass this system by using a device that can detect the signal.
It is evident that the transponder is a good option. Every car owner should take this into consideration if they wish to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the car remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with one another and the car. These frequencies are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
You can program a keyfob in a variety of ways depending on the model and make of your car. It is possible to do this yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on your key fob the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver then compares this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle, even though they appear similar. This is to safeguard the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer service department. Some fobs from the aftermarket, especially ones for older models that have less advanced systems can be programmed without the need for a dealer.
