i cleaned my oven and it won't open

Hi

I went to clean my oven, I did the quick clean. Just as the door locked I realized I forgot to take out a peice of tin foil. It seems as though I interrupted the cleaning cycle and jammed the cleaning cylce.

I can't use my oven, it won't open. Stovetop is fine. Its a gas stove.

 

Please help
