Hi adam, my name is jamie, my missus recently bought a vx acclaim and the battery in both keys is buggered. one of her friends took one key apart and hooked up a wire to piggy back another battery on top to get power through the key to unlock the sec. sys. i read in an old post you figured how to bypass this... can you please tell me as im sick of sitting in the missus car in this heat wave trying to get it to unlock the sec system so she can go do her daily thing. any help would be greatly appreciated. a permanent turn off would be great. thanks heaps mate
