Using a Key Programmer Modern key fobs aren't simply keys; they can communicate with a vehicle to start it, open the rear hatch, and more. To accomplish this, they need to be programmed. Car dealerships, your car manufacturer and auto locksmiths all offer key programming services. You can also do it yourself, if you have the right equipment. What is a key programmer? A key programmer is a device used to recode the transponder in the fob or key of a car or truck, or any other vehicle. This is required when the new key or fob needs to be programmed. It's also common in the event that an existing key or fob has been stolen or lost. The device essentially reprograms the digital signature on the chip inside the key to match that of the vehicle and enable it to start. Certain cars are equipped with electronic immobilizers which prevent theft by preventing the engine from being started without the correct 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. The system will shut off if it doesn't. This kind of system has been found to be effective in reducing automobile theft and is now required for many models of cars by the manufacturer. Most anti-theft systems are controlled by a module installed in the engine compartment or instrument cluster or ignition lock. In some instances the modules require special keys that are programmed by experts to function with the antitheft system. This is usually done by a dealership or locksmith using computers. While it is possible to reprogramme certain keys and fobs at home but it is not advised unless you are a highly skilled technician in the field of automotive. This is because a wrongly programmed key can cause the vehicle to fail to start, run or even be destroyed. The majority of automakers have a very precise procedure to program keys.

In addition, it also offers you support and documentation that can aid you in your day-today business operations. How do I program an electronic key?
