Fold the paper over the the metal part of your front door key. Make a charcoal rubbing of the key's ridges with the pencil.
Remove the key from the paper. Cut out the charcoal rubbings of the key and glue them to the ice cream stick, one on each side.
Press the tip of the knife onto the shaded sections of the paper, creating indentations on the ice cream stick identical to those on the original key. Cut a straight ridge down the middle of the ice cream stick with the knife.
Insert the ice cream stick into the front door lock. Twist it carefully and you will find that the door opens just as it would if you were using a key.
