Key programmer is a device that allows you to change the transponder code in the key of a truck or car fob or key. This process is required when the fob or key must be programmed. It is also necessary when an existing fob or key is stolen or lost. The device basically reprograms the digital signature of the chip inside the key to match the signature of the vehicle and enable it to begin.
Certain vehicles come with electronic immobilizers that prevent theft by stopping the engine from starting without the correct key. The system checks whether the fob or key is digitally signed. The system will shut down when it isn't. This type of system is effective in reducing car theft and has been made compulsory for various models of automobile by the manufacturer.
These systems can be controlled by a device that is placed in the vehicle’s engine or instrument panel or ignition lock. In some instances the modules require specific keys that have been specifically programmed by professionals to function with the anti-theft system. This is typically done by a dealer or locksmith who uses a computer.
While it is possible to reprogramme certain fobs and keys on your own however, it is not recommended unless you're a highly skilled automotive technician. This is because a wrongly programed key could cause the vehicle to fail to start, run or even be destroyed. Most auto manufacturers have a particular procedure to program these kinds of keys.
