this is the best i can do for a pic, hope it helps.
this is the only entry possible. its a back door to a new edition of a building. the only other way in has a motion sensor for an alarm but this way has no alarm from the door to where the money is. also the only other way in is on a well lit main drag through town my entry is in a dark alley and is covered my a small shelter/porch. just all the way around seems the best option. windows are bars over from the inside and are 8ft off the ground so no option there. i was almost thinking the bast way in is to drill a half inch hole about an inch under where the bar runs across the door. then have some 1/4" rod bent up that has 2 90 degree bends in it to form kind of a "z" shape except they'd be 90's slip it in through the hole and by pushing down on the end thats on the outside of the door would in turn push the bar up on the inside but i'm not sure how well that would work.
hinges are on the inside
another thing i was thinking was to just cut across the door with a sawzal so i don't have to fuck with the lock or the bar but i think that would far exceed the noise i'm willing to make.
this is a one time deal no room for error i either pull it off or i never try again and i'm looking at between 5k-10k cash so i'd really like to pull it off.
and like i say i can get exact messurements before i do it so from the outside i'll know exactly where the bar is height wise and exactly how far in it is.
any other idea's?
