There is usually a (PITA) proceedure to stop it each time it starts to make annoying noises, if it is factory fitted. Is the battery covered under warranty? I always thought they are supposed to last at least 5 years (this is my first car with remote entry, the others have been after market systems). The battery is dead in DeWayne's key remote and he wants to replace it himself.
