Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to start it up, open the rear hatch and more. To accomplish this, they have to be programmed together.
Car dealerships, your car manufacturer, and auto locksmiths can all provide key programming services. You can do it yourself using the right tools.
What is a key programmer?
A key programmer is a device used to recode the transponder on the fob or key of a car truck or other vehicle. This procedure is needed when the new key or fob has to be programmed. It is also often necessary in the event that an existing fob or key has been lost or stolen. The device reprograms the chip inside the key to match the digital signature of the vehicle which allows it to begin.
Certain cars are equipped with electronic immobilizers that prevent theft by preventing the engine from being started without the correct key. This is done by having the car's security system verify that the key or fob has the right digital signature. The system will shut down when it isn't. This kind of system is efficient in reducing theft of automobiles, and has been made compulsory for a variety of models of cars by the manufacturer.
Most anti-theft systems are controlled by a module that is installed in the vehicle's engine, instrument cluster, or ignition lock. In some cases the modules require special keys that have been designed by experts to work with the anti-theft system. This is usually carried out by a dealer or locksmith through computers.
Although it is possible to reprogramme some fobs and keys by yourself however, it is not recommended unless you are a highly skilled automotive technician. This is because a wrongly programmed key can cause the vehicle to fail to run, not start, or even be completely destroyed. The majority of automakers have a very precise procedure for programming these keys.
It is recommended that if you want to offer key programming as a part of your service offerings, you obtain an LSID.

A dealer will typically need to have the VIN number of your vehicle in order to do this, and will usually charge a fee for it. You can save money by giving your dealer a copy, which you'll be capable of obtaining from the DMV of the majority of states.
For certain cars you may also be able to reprogram your own key if you already have a working key that works with your car. This is known as the master key method and it is applicable to certain vehicles to program an additional key. If you own a GM car, for example you can insert your key into the ignition until the security light goes off. Once that happens you can take out your working key, and then insert the new one to program it.
You can also purchase an specialized EEPROM key programmer which is a costlier but more effective method to program car keys.
