reset window lock screen with bat file?

Hi,

1. I installed RohosLogonKey. It added a logon option to the lock screen and save a "logon key" to a usb (I save it to my c: harddrive) . So that my computer can automatically logon to window. (my computer using win10 )
2. I also setup a program called btprox. Its job is to delete the "logon key" when loose bluetooth connection and lock the computer, then copy the "logon key" to its location when the bluetooth device is connected.
My problem is when the computer is locked on step 2, Rohos will look for the logon key, if it cannot find the key, it stops. When the bluetooth is back and the "logon key" is copied to its location, Rohos will not unlock the computer. It seems like it won't read the "logon key". If I manual login, Rohos will work again.

So my question is, can a bat file restart the lock screen, so that Rohos will tried to look for the "logon key"?

@caledonken Thanks.
The article does not have what I'm looking for, but I got some useful commands from it.
