Windows 10: Automatically locking BitLocker volumes

Is there an easy way to have certain BitLocker volumes lock automatically after a period of user absence and lack of reading/writing to the volumes? Perhaps a utility that does this?

I've been playing with a scheduled task, but so far, it locks the volumes when I don't want them to, and is oblivious to when the volumes are being used.

Edit: I guess I will just use Shutter, which I have been using for a long time, but never for this. I'm guessing I will need to run Shutter with elevation for this (i.e. manage-bde.exe -lock -fd) to work. I was hoping to use a more dedicated utility, without having to learn how to do it in AutoHotkey or something.

Bitlocker has locked me out of windows during doing a full reset on surface book.

Bitlocker has locked me out of windows during doing a full reset. Don't have keycode or access to any windows directory including being prevented from doing full factory reset because it appears that the volume where the instalation copy of windows is stored,
seems to be 'Volume 3', is the only volume listed twice over, and both are locked by bitlocker. The system is a surface book with windows 10.

How do I work around this to do a full factory reset?
