In Reply to: so if they have copies posted by bintang bob on Wednesday, 2. December 2009 at 09:05 Bali Time:
there will only be one copy of "the" safe key which you get when you sign for the box,but the box cannot be opened with just your key it also needs a master key which they keep,there is a possibility that they have a spare master key somewhere in case the original goes missing but a box cannot be opened with a master key only it takes both keys so if you lose yours they have to drill it out and replace it with a new lock hence the fairly large charge.
