Using a Key Programmer
Modern key fobs are more than just act as keys. They communicate with the vehicle to turn it on, open the rear hatch, and more. To do this, they must be programmed together.
All automotive dealerships, auto manufacturers, and auto locksmiths offer key programming. However, you can also do it yourself if you have the right equipment.
What is a key programmer?
A key programmer is a device used to recode a transponder on a key or fob for a car, truck or another vehicle. This procedure is needed when the new fob or key needs to be programmed. It is also often necessary in the event that an existing fob or key is stolen or lost. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle and allow it to start.
Certain cars are equipped with electronic immobilizers that stop theft by stopping the engine from running without the proper key. The system checks to determine whether the fob or key is digitally signed. The system will shut down in the event that it doesn't. This type of system is very effective in reducing car theft and has been made compulsory for various models of automobile 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 instances these systems require specific keys that are programmed by experts to work with the anti-theft system. This is typically done by a dealership or locksmith through a computer.
While it is possible to reprogram some fobs and keys on your own however, it is not recommended unless you're a highly skilled technician in the field of automotive. The reason is that a poorly programmed key could cause the vehicle to run, not start or be destroyed. The majority of auto makers have a precise process for programming keys.
