Bless your heart, I know this can be a very frustrating type of situation but it really is a simple fix. If I understand you properly, you pulled off both of the door knobs but the "bolt" section in the middle is still in place. IF this is the case, you can start by trying to put the door knob on the side you are on, back in the hole through the door the same way it came out and it should turn like normal to open the door. If not, then get a flat head screwdriver and insert it in the middle of the opening in the door (usually there is a square opening within the metal that is still there. Using the screw driver head, turn the square either clockwise or counter-clockwise until you find the the bolt in the door pulls into the door.

I hope this helps. Let us know what happened.

Hugs 'n hammers,
