Using a Key Programmer
Modern key fobs are more than just keys. They communicate with vehicles to start it and open the rear hatch, and so on. To accomplish this, they have to be programmed.
All automobile dealerships, auto makers, and auto locksmiths offer key programming. You can do it yourself with the right equipment.
What is a key programer?
A key programmer is a device used to recode a transponder on the fob or key for a car or truck, or any another vehicle. This is required when a new fob or key needs to be programmed. This is usually required when a fob or a key is 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 begin.
Certain 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. The system checks to see if the key or fob is digitally signed. If it doesn't, the system will shut down. This type of system has been proven to be effective in reducing automotive theft and has been made mandatory for various models of vehicles by the manufacturer.
Most of these anti-theft systems are controlled by a module installed in the engine compartment, instrument cluster, or ignition lock. In some cases these systems require specific keys that are programmed by experts to work with the anti-theft system. This is typically carried out by a dealer or locksmith using the use of a computer.
It is possible to reprogramme certain fobs and keys yourself but it isn't recommended until you are an experienced technician in the field. 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 specific method for programming these types of keys.
It is advised that if you intend to offer key programming as a part of your service offerings, you obtain an LSID. This credential allows you access to the database of key and immobilizer codes along with details about the product. Having this access allows you to create and test new keys for customers quickly and effortlessly. It also provides crucial documentation and support that will aid you in your everyday business operations.

Therefore, before you attempt to do this yourself you should first talk to an expert or locksmith for instructions.
