The blades get a final cut in before Grimmgang disables them, and after several minutes of work, the door is opened. It seems the locks were meant to keep things in rather than out; as far as you can tell, there is no automatic reset attached to them. You do uncover a mechanism inside the door that appears to link to the blades; it is rather unnecessary now, and you suspect that a failure to manipulate it correctly would be painful, but the option is there if desired.

The other side of the door features another dark staircase curving away to the right; you estimate that its descent will place you relatively close to the magma vein.
