Using a Key Programmer
Modern key fobs do more than just function as keys. They communicate with the vehicle to turn it on and open the rear hatch, and more. To do so they must be programmed to work with each other.
All automotive dealerships, auto manufacturers, and auto locksmiths offer key programming. However, you can do it yourself if you have the right equipment.
What is a key programer?
Key programmer is a tool used to change the transponder code in the car or truck key or fob. This is needed when a new fob or key has to be programmed. It is also often necessary in the event that an existing key or fob has been lost or stolen. The device reprograms the chip within the key to match the digital signature of the vehicle which allows it to begin.
Some vehicles are equipped with electronic immobilizers which prevent theft by stopping the engine from being started without the proper key. This is accomplished by having the car's security system examine to ensure that the key or fob has the right digital signature. The system will shut down when it isn't. This kind of system has been proved to be effective in reducing automotive theft and has been made mandatory 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, instrument cluster, or ignition lock. In some cases, these modules require special keys that are specifically created by professionals to function with the anti-theft system. This is typically performed by a dealership or locksmith using a computer.
While it is possible to reprogram some keys and fobs at home but it is not advised unless you're an skilled technician in the field of automotive. The wrongly programmed key could cause the vehicle to not start, or not to run or even be destroyed. The majority of auto makers have a particular procedure for programming these kinds of keys.
It is advised that if you intend to offer key programming as part of your service offering you get an LSID. This credential gives you access to an encrypted database of product information as well as keys and immobilizer codes via the NASTF's Secure Data Release Model. This access allows you to quickly and easily program and test a new key for customers. It also provides crucial documentation and support that can assist you in your day-to-day business operations.
