you just gotta get to that point where you have a big ring of keys and you either find one that works or one that at leest works with some jiggling and in/out-ness.. juat ask john rainbo i got both of his daytonas open with the wrong key that went in the hole off of my own key ring.. little wiggle giggle in and out and viola..
i keep telling myself im going to get some more bump keys or make some but just havent gottsn to it (get on youtube type in lock bumping) also a pickset would work well too. someyear ill have more of that neat krap..
