A keyprogrammer is a device that can recode the transponder chip on the form of a new key fob or mechanical key. It is also able to copy the data of an existing key and allow duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's a small plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is taken up by an antenna attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for the car you have.
This stops the vehicle from starting by hot-wiring, or by manipulating. The chip in the key also confirms that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys appear like regular metal keys but have a plastic cap. The chip is housed within the plastic part of the key, and there are a few different cuts that can be found on these keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as correct it will turn off the car immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and alert you with flashing lights and siren. This is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A determined and skilled thief could still bypass this system with a specially designed 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 vehicle owners should consider if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding a car or turn on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted through an antenna that is located in the middle of the key. The signal is encrypted to prevent others from stealing or stealing the signal.
You can program a keyfob in a variety of ways depending on the make and model of your car. You may be able to do it yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on your key fob the microchip inside sends a code to the car's receiver it is paired with. The receiver then compares this information with the 'allowed' signals on the fob and either opens or locks the door. If the information does not match the signals, the car will not be allowed to drive.
Once the car is associated with a particular fob, it will only accept signals from the device. In turn, other fobs won't be able to work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place with the expertise to prepare an appropriate replacement fob is a dealer's service department. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed with out the need for a dealership.
