Using a Key Programmer
Modern key fobs aren't simply keys; they can communicate with vehicles to start it and open the rear hatch, and more. To do so they must be programmed to work with each other.
All car dealerships, auto manufacturers and auto locksmiths can provide key programming. But you can do it yourself if you have the right tools.
What is a key programer?
A key programmer is used to reprogram a transponder on the fob or key of a car truck or another vehicle. This procedure is necessary when the fob or key has to be programmed. It's also common in the event that an existing fob or key is stolen or lost. The device reprograms the chip inside the key to match the digital signature of the vehicle which allows it to begin.
Certain vehicles come with electronic immobilizers which prevent theft by preventing the engine from being started without the right key. The system checks to determine if the key or fob is digitally signed. If it doesn't, the system will shut down. This type of system is effective in reducing car theft and was made mandatory for various models of automobile by the manufacturer.
These systems can be controlled by a device that is placed in the vehicle's engine or instrument panel or ignition lock. In some instances they require keys that have been specifically created by professionals to function with the anti-theft system. This is usually carried out by a dealer or locksmith via computers.
While it is possible to reprogramme some fobs and keys by yourself however, it is not recommended unless you're a highly skilled automotive technician. This is because a wrongly programmed key could cause the vehicle to fail to run, not start or be destroyed. The majority of auto makers have a particular procedure for programming these kinds of keys.
It is recommended that if you plan to provide key programming as part of your service offerings you get an LSID. This credential gives you access to the database of immobilizer and key codes along with information about the product. This allows you to quickly and easily program and test a new key for customers. It also provides crucial documentation and support that will help you with your day-to-day business operations.
