So my stupid roommates not only put tape in the door but also took the knob off. I closed it while doing laundry and they dont know where the knob is or pieces to open it. Can yall help
If you can't pry the latch tongue out of the striker plate (door frame) with a butter knife or a credit card, then you must somehow grasp that C-shaped piece and pull it toward the center of the door. Find a screwdriver, knife, or similar tool that is just a bit larger than the space between the arms of the C, insert and twist it to get a grip.
As even your roommates now know, tape is the wrong solution here. The proper procedure is to remove the mechanism entirely. Scrape off the remains of the tape and remove the two screws beneath. Insert almost any tool into the C and push the entire thing out of the door.
