What i was thinking, was the new eleventh doctors screwdriver. It would have 2 mods, Extended, and not extended. The non-extended mod would just Activate JVS switches. Extended would Open All JVS doors, (Depending if the door is blocked, or locked). To activate the extended mod, the player with the screwdriver would double-click, and it will extend, He/She would then hold down the mouse to activate the screwdriver, which would emit a green light,and sound*. For non-extended, you would just need to hold down the mouse, and the green light would emit, along with the sound.
Here is the link to the sonic sound and a picture:
