Wouldnīt mechanics be also useful? for bypassing security? If so, here it is:
1d20+15=19 +1d6(1) FP =20 (insert several curses)
not sure if the utility beltīs toolkit counts as giving +2 to mechanics or only as "having toolkit", but if applicable, it would give another +2 to the roll
EDIT: forgot the link, so I gave it back and gave in an FP
