i think in lock box cases you need a warrant to open a specific box so unless he had that box out his grand daughter they can't go willy nilly and try the key on everything (i think).
besides, i doubt he even had the key with him as it was a 1 time deposit that was going to sit there.
even so, i believe i heard someone say in the episode that mike lost his pay to the DEA twice so they have some portion of that money. really hard to say if any of it is safe.
