I need some ideas on locks

[Nraman]

I finally got a storm shelter. All steel, bolted on the slab etc.
I need to install a couple of good quality locks on the door and get dual use out of it as a safe.
The door is 3/16" steel and weighs around 500-600 lbs. Don't know much about locks, any ideas welcome.
Also ideas on how to drill a 2 1/8" hole, I don't think regular hole cutters can handle the job.
I am thinking about a set of two deadbolts.

Having lived thru a couple of tornados, a locked cellar is dangerous. Material things can be replaced, lives no so much.

I plan to lock it when I am not there.

Plasma cutter for the 2 1/8" hole.

It would be nice if I had one.

Is this an above ground shelter inside your house or what?

Surely there's an OSAer on here in the Tulsa area with one who could lend a hand.

I have a plasma cutter I could come over with if ya want but a Bi metal hole saw would do the trick with a little patience

do you have any family who might be at home while you are not there?

For the holes I would go to the tool rental place and rent a mag drill and a bit. About as perfect as drilled holes can get. I think dead bolts would work better than pad locks plus not as much a chance of getting locked in.
