Using a Key Programmer
Modern key fobs are more than just keys. They communicate with a vehicle to start it and open the rear hatch, and much more. To do this, they need to be programmed.

What is a key programmer?
A key programmer is a device that allows you to reprogram the transponder on the car or truck fob or key. This is needed when a new fob or key must be programmed. It is also necessary when an existing key or fob has been stolen or lost. The device reprograms the chip in the key to match the digital signature of the vehicle which allows it to begin.
Certain vehicles come with electronic immobilizer systems that prevent theft by stopping the engine from starting if it is not equipped with the correct key or fob. This is done by having the system verify that the fob or key has the correct digital signature. The system will turn off when it isn't. This kind of system is effective in reducing automobile theft, and has been made compulsory 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 instrument panel, instrument panel or ignition lock. In some cases the modules require specific keys that are programmed by a professional to function with the anti-theft system. This is usually carried out by a dealer or locksmith using computers.
It is possible to reprogramme certain fobs and keys yourself but it isn't recommended until you are an experienced automotive technician. A wrongly programmed key can cause the vehicle not to start, fail to run or even break. The majority of auto makers have a very precise procedure to program keys.
If you want to include key programming in your service offerings, it is recommended that you obtain an LSID (Locksmith Service ID). This credential gives you access to a secure database of information about the product and keys and immobilizer codes via the NASTF's Secure Data Release Model. Having this access allows you to program and test new keys for customers quickly and effortlessly. It also provides important documentation and support that will assist you in your day-to-day business operations.
