it's doable, members have done it, i need to do it to one of mine, and i don't have the stones to try. on the main page and if you search the tales of joy and heartbreak are laid out. it involes prying the two halves apart by wedging a spreading device into the blade grove and praying from what i can recall. please let us know how you make out. the internals seem intimidating to anyone without a degree in electrical engineering and i'm scared to death of them. one of the members posted some pics when i asked about this recently. start there by searching fob or something to that effect.
