Using a Key Programmer
Modern key fobs aren't simply keys; they can communicate with vehicles to start it or open the rear hatch, and much more. To accomplish this, they have to be programmed together.

What is a key programer?
A key programmer is used to reprogram the transponder on the fob or key of the vehicle truck or other vehicle. This process is required when a new fob or key must be programmed. It is also often necessary in the event that an existing fob or key has been lost or stolen. The device basically reprograms the digital signature of the chip inside the key to match the signature of the vehicle and allow it to start.
Some vehicles are equipped with electronic immobilizers that prevent theft by preventing the engine from being started without the right key. This is done by having the system verify that the fob or key has the right digital signature. If it doesn't, the system will shut down. This kind of system has been proven to be effective in reducing automobile theft and has been made mandatory for many models of cars by the manufacturer.
The majority of these anti-theft systems are controlled by a module installed in the vehicle's engine instrument cluster, instrument cluster, or ignition lock. In some cases these systems require specific keys that have been programmed by professionals to work with the antitheft system. This is typically performed by a dealer or locksmith who uses a computer.
It is possible to reprogramme certain keys and fobs yourself but it isn't recommended until you are an experienced technician in the field. A wrongly programmed key can cause the vehicle to not start, fail to run or even to be destroyed. The majority of auto manufacturers have a specific procedure to program these keys.
If you are planning to include key programming into your service offerings it is recommended you obtain an LSID (Locksmith Service ID). This credential grants you access to an encrypted database of information about the product and key and immobilizer codes through the NASTF's Secure Data Release Model. Having this access allows you to program and test new keys for customers quickly and easily. Additionally, it provides you with important support and documentation that will assist you in your day-to-day business operations.

For instance, if are driving an GM vehicle, insert your working key into the ignition and switch it on until the security light turns off. After that then you can remove your working key and then insert the new one to program it.
