Using a Key Programmer
Modern key fobs aren't just keys; they communicate with vehicles to start it, open the rear hatch, and much more. To do so they must be programmed to work with each other.
All automotive dealerships, auto manufacturers and auto locksmiths can provide key programming. However, you can do it yourself if you have the right tools.
What is a key developer?
A key programmer is a device used to recode the transponder on the fob or key for the vehicle, truck or other vehicle. This procedure is needed when the new key or fob needs to be programmed. This process is often required when a fob or a key is stolen or lost. The device basically reprograms digital signature on the chip inside the key to match the signature of the vehicle, and allows it to start.
Some vehicles come with electronic immobilizers that protect against theft by preventing the engine from starting if it is not equipped with the correct key or fob. This is accomplished by having the car's system examine to ensure that the fob or key has the correct digital signature. The system will turn off in the event that it doesn't. This kind of system is efficient in reducing automobile theft, and was made mandatory for various models of automobile by the manufacturer.
These systems can be controlled by a device that is placed in the vehicle's engine, instrument panel or ignition lock. In some cases the modules require specific keys that are specifically designed by professionals to work with the anti-theft system. This is usually done by a dealer or locksmith with computer.

The reason is that a poorly programed key could cause the vehicle to start, run, or even be completely destroyed. The majority of auto manufacturers have a very precise procedure to program keys.
