What is a key-programmer?
Key programmer is a device that allows you to change the transponder code in the car or truck key or fob. This procedure is necessary when the fob or key has to be programmed. It is also necessary when an existing fob or key is stolen or lost. The device reprograms the chip in the key to match the digital signature of the vehicle, allowing it to start.
Some vehicles come with electronic immobilizers that protect against theft by preventing the engine from running without the correct fob or key. This is done by having the car's security system check to make sure that the key or fob has the right digital signature. If it doesn't, the system will shut down. This kind of system has been found to be effective in reducing automobile theft and has been made mandatory for a variety of models of cars by the manufacturer.
These anti-theft systems can be controlled by a module that is installed in the vehicle’s engine or instrument panel or ignition lock. In some cases, these modules need special keys that are programmed by experts to work with the antitheft system. This is usually performed by a dealership or locksmith via computers.

The reason is that a poorly programed key could cause the vehicle to fail to run, not start, or even be completely destroyed. Most auto manufacturers have a very specific procedure for programming these types of keys.

For certain vehicles you may also be able to program your own key if you have a second working key that works with your vehicle. This method is called the master key method, and it is applicable to certain vehicles in order to program an additional key.
