How do I unauthorize a key fob that I lost?

Each of your key fobs is programmed specifically to work with your car. No other key fob will work with your vehicle. If you lose your key fob, or fear that it may be stolen, you want to unauthorized it, so that no one can use it to access your vehicle. The only way to do this is to take your vehicle to a dealership, where they will erase all previous key fobs from the vehicle’s system, and authorize a new key(s) and any previous key for the vehicle that you physically have.
