Using a Key Programmer
Modern key fobs go beyond just keys. They communicate with a vehicle to start it, open the rear hatch, and much more. To do this, they have to be programmed.
All automotive dealerships, auto manufacturers, and auto locksmiths offer key programming. You can also do it yourself, if you have the proper equipment.
What is a key developer?
A key programmer is a tool used to recode the transponder in the car or truck fob or key. This procedure is necessary when a new fob or key needs to be programmed. This process is often required when a fob or a key is lost or stolen. The device reprograms the chip inside the key to match the digital signature of the vehicle and allows it to start.
Some vehicles come with electronic immobilizer systems that prevent theft by preventing the engine from starting if it is not equipped with the correct fob or key. This is done by having the car's security system examine to ensure that the fob or key has the correct digital signature. If it does not, the system will shut down. This type of system has been proved to be effective in reducing the incidence of theft and was made mandatory for a variety of models of cars by the manufacturer.
The anti-theft system can be controlled by a device that is placed in the vehicle's engine, instrument panel or ignition lock. In certain instances the modules require specific keys that have been specifically programmed by an expert to work with the anti-theft system. This is typically carried out by a dealer or locksmith via computers.
While it is possible to reprogramme some keys and fobs by yourself, it is not recommended unless you are a highly experienced automotive technician. This is because the wrong programed key could cause the vehicle to fail to run, not start, or even be completely destroyed. The majority of auto manufacturers have a specific procedure for programming these keys.
It is recommended that if you want to offer key programming as part of your service you get an LSID. This credential allows you access to a database of key and immobilizer codes and product information. This access lets you quickly and easily program and test a new key for customers. Additionally, it offers you assistance and documentation to help you with your day-to-day business operations.

After the security light is out, you can take off the working key and then insert the new one.
