These tools are generally not available to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.

These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured in the last 20 years. It's a small plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your vehicle.
This stops the vehicle from starting by hot-wiring or altering the key. The chip in the key also confirms that you are the legitimate owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is contained within the plastic part of the key, and there are a few different cuts that can be found on the keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will then get received by the chip and cause it to send a signal back to the car. If the computer onboard the car detects the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will alert you with flashing lights and siren. This feature is intended to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still bypass this system by using a specific device that intercepts the signal.
As you can see, there are quite a few advantages to getting a transponder key. Every car owner must take this into consideration if they wish to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. A lot of these additional features may seem convenient however they could make it difficult for you to keep the keys to your car.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted through a small antenna located in the center of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
There are a few different ways to program a key fob, based on the make and model. It is possible to do this yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you hit the button on a key fob the microchip inside sends a code to the car's receiver that it is paired with. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car door. If the information does not match the signals, the car will not be allowed to run.
Once the car has been associated with a particular fob, it will only accept signals from the device. Other fobs won't work with the car, even if they look like. This ensures the security of the computer system in the car and blocks unauthorised key fobs from taking control of it.
Most newer car dealerships will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
