My friend lives in an apartment and has an underground corridor running through the storage rooms of the houses. We rigged the door from his room to the storage room so we could get in if it was locked. But we didn't think about rigging the door from the storage room to the corridor. So i thought of a few ways we could open the door and this was the simplest one.
I added a video because no one can figure this thing out apparently.
Step 1: Stuff You Need.
1-laminate card(gift cards work best. I used an itunes card.)
3-a locked door that needs getting into
Step 2: Cut the Card.
Step 3: Unlock the Door
(hint: if the door opens away from you, you are probably going to have to push the card. if the door opens toward you, chances are you are going to have to pull the card. unless some idiot put the door knob on backwards.)
