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

Key Programmers
Modern automobiles often require a key programming procedure to start the system of the vehicle and allow the vehicle to start. In some instances, the key must be configured by the dealer or an auto locksmith. This is because the key could not function properly, or it will not start the car at all. This is because the key hasn't yet been programmed into the car's system. This could be costly. It is best to have two keys that are compatible for the modern automobile so that you can program the replacement key if needed.
A keyprogrammer is a device that can recode the transponder chip into an entirely new key fob or mechanical key. It can also clone information from an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers on the market. They are available in a variety of shapes, sizes and colors. Some are inexpensive and others may cost thousands of dollars. Certain models are specifically designed for certain kinds of vehicles and provide advanced diagnostics for the vehicle's electronic systems.
Refer to the owner's manual of your vehicle to learn how to program a key for your vehicle. Certain manufacturers employ proprietary technology that makes sure that the dealership is the only entity that can make new keys. However, other manufacturers make it fairly easy for anyone to do it on their own.

Transponder Chips
Transponder chips are likely to be found in cars manufactured within the last 20 years. This is a little plastic piece in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.
This prevents the vehicle from being started through hot-wiring, or by manipulating. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on these keys: a regular standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be received by the chip and cause it to transmit a signal to the car. If the computer onboard the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to deter people from trying to hack into the vehicle, but it's not a 100% security measure. A skilled and determined thief could still be able to escape this security system by employing a device designed to intercept the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should think about if they want to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making chirping sounds to help find the car in a parking space keys of today can also turn on the heated steering wheel or roll down all of the windows with a single button click. These extra features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. The frequencies are transmitted through a small antenna located in the middle of the key. This signal is encrypted to prevent others from stealing or modifying the signal.
There are many ways to program a key fob based on your vehicle's model and make. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob, the microchip transmits an indication to the receiver in the vehicle with which it is paired. The receiver compares this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information does not match the fob's information, the car won't be allowed to operate.
When a car is connected with a specific fob it will only accept signals from that specific device. In turn, other fobs won't work with the vehicle even though they look the same. This is to safeguard the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of the dealer. Some fobs from the aftermarket, especially those for older models that have less advanced systems, can be programmed without the need for a dealer.
