These tools are not generally accessible to the general public and are only used by professionals. This type of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.

Transponder Chips
If your car is made in the last 20 years, chances are it has a transponder chip inside of it. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When it is activated by an electro-magnetic field the chip emits a low-level signal. This signal is then taken up by the antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your particular car.

A circuit inside the induction coil emits signals when the transponder is placed in the the ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the onboard car computer detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is intended to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined criminal might be able bypass this system by employing a device designed to detect the signal.

Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding the car or switch on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. These frequencies are sent by a small antenna within the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
There are several ways to program a key fob based on your vehicle's make and model. You can sometimes do this yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob the microchip sends an indication to the receiver inside the vehicle that it is paired. The receiver compares this information with the 'allowed' signals stored on the fob and either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is paired with a specific fob, it can only receive signals from that device. In turn, other fobs won't work with the vehicle even though they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.
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 knowledge that is only available in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
