Whoa!? Was a little busy this weekend and never checked back with this thread, too bad, since it looks like I missed out on some expert tool box advice, too bad his comment got deleted, lol.
As for the box, I got it unlocked. It was a million times easier than I thought it might be. I simply opened the drawer below, slid a crowbar to the back, picked up the offending bar by the locking tab and opened the previously locked drawer. When I have more time I will remove the bars as Gary S suggested.
And for what it's worth, I have 2 of the Kobalt 5 drawer boxes and they have worked perfect for me. I bought them both on clearance (at different times) and have about $150 total in them, including new drawer liners. I bought the first one a couple of years ago to replace an old StackOn (!! Wonder what 1984GMC thinks about that !!) I'm more than happy with them.
