A keyprogrammer is a device that can recode the transponder chip in the form of a new mechanical or key fob key. It also can clone data from an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

Transponder Chips
If your car was manufactured within the last 20 years, it is likely that it contains a transponder chip within of it. It's the tiny plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the right one for the car you have.
This is the reason why doing hot-wiring or altering the vehicle's ignition system to get it started. The chip inside the car key confirms that the owner is the one who owns the vehicle. This helps to prevent car theft.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip is contained within the plastic part of the keys. There are several different cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
The circuit in the induction coil emits signals when the transponder is inserted into ignition barrel. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.

If the car does not recognize the transponder signal as the right one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and determined thief could still evade this system using a special device that detects the signal.
As you can see there are quite a number of benefits to having transponder keys. This is something that all car owners should think about if they want to protect their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate the car in a parking space, today's key fobs can also turn on the heated steering wheel or open all windows with a single button click. A lot of these additional features may seem convenient, but they can also make it harder for you to keep track of your car keys.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted through an antenna in the center of the key. automotive key programming is encrypted to block other key fobs from intercepting or replicating the signal.
There are many ways to program a key fob based on your vehicle's model and make. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is paired with. The receiver then compares this information with the signals that are allowed in the fob and then either opens or closes the door. If the data does not match the signals, the car will not be allowed to run.
Once the car is paired with a specific fob, it will only accept signals from that specific device. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. This is because the only place with the knowledge to create an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for an authorized dealer.
