Doors – How to open a stuck cellar door

doors

I have a door in my cellar that is stuck. Of course, my tools are all on the other side of said door (but I guess my credit card isn't, so that is a plus).

It has no lock and I cannot run anything between the door frame and the door as it has a kind of right-angle shape to it (so the front bit of the door overhangs the frame).

It is also made of metal. (honestly, I think the people that built this house were preparing for the apocalypse or something).

It is fairly cold outside (about -9 C) and hence the cellar is also not warm, my theory as to why it is stuck now runs into the realm of metal shrinking when it gets cold.

Irrespective of why, I need to get into that room, so does anyone have any idea what I should do?

I am thinking that my only option is to remove the hinges somehow but as you can see they are monsters, or trying to heat up the door (maybe pray for warmer weather but as I live in Austria, that will likely be some months off).

Update

I put a wrong comment on this question to Mikes. Sorry Mikes. I performed some more investigation, using a Christmas card I tore two strips and ran them along the edge of the door (one from the bottom up and one from the top down) and they both stopped at the handle thingie. I then turned the handle and tried to move the card – it did not move. Hence I think the handle is not moving the triangular metal thingie in when it turns.

It is not flapping, however, which makes me think that removing the handle (something I think I can do with a kitchen knife and a pair of my wife's tweezers) will not help me – what do you think?

Instead I took an out of date roadside rescue service membership card and fashioned the following tool:

Here it is being tested on a door that is the same and thankfully open:

I noticed a small gap thus on the top of the door where I can slide it down:

The problem with this approach is that the tool is too thick to fit between the frame and the bit I have to push in! Arrrggh. It needs to be double-thickness because otherwise it will not be strong enough to push it in (I tested this).

I think, therefore, that I will go to the hardware store and see if I can get thin bit of metal bent into the shape I need. I don't know if this will be possible.

Does anyone have any other ideas?

Best Answer

Try a set of floor tile lifters that have a handle and strong suction cups on each end. Here's a link. http://www.amazon.com/Red-Double-Suction-Tile-Lifter/dp/B00HDP84SU

You may be able to do the same thing with a couple of plungers if you can get a good seal. Good luck!
