A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It can also clone information from an existing key to make duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface for working with an immobilizer system. There are many various kinds of keyprogrammers that are available and they come in all shapes and sizes.

Transponder Chips Transponder chips are likely to be found in cars that were manufactured within the past 20 years. This is a little piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle. The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car. This prevents the vehicle from being started through hot-wiring, or by tampering. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle. Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is located inside the plastic portion of the keys. There are various cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe. The circuit in the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to start. If the vehicle does not recognize the transponder signal as being the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This function is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief could still evade this system by using a specific device that intercepts the signal. You can see that the transponder is an excellent option. This is something that all car owners should think about if they want to protect their investment and minimize the risk of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely, or making noises to aid in finding the car in a parking space keys of today can also switch on the heated steering wheel or open all windows with a single press. A lot of these additional features might seem useful however they could make it harder for you to keep the track of your car keys. Key fobs communicate with one with the car via radio frequencies that are transmitted via an antenna in the middle of the key. The communication is encrypted, which helps to stop others from stealing and re-transmitting the signal. There are many ways to program a key fob based on the vehicle's make and model. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or an additional one. When you press a key fob's button it transmits an encoded code to the car's radio that it is paired with. The receiver compares the information with the permitted signals 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 is associated with a particular fob, it can only receive signals from the device. In turn, other fobs won't work with the vehicle even if they look the same. This safeguards the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control of it. Most newer car dealerships will only work with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge which can only be obtained in the dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
