One thing to verify with this style of coil spring lock is the screws that hold the "guard plate" (as you called it) are not loose but snug. If they get loose, then pieces inside the lock get out of position, such as the fly. (don't ask how I know) Tomorrow, if possible, I will remove the lock from my TC Renegade (same type), remove the "guard plate" and take a picture of the parts positioning for comparison.
