She finds some keys.

Chloe found some keys on a wall hanger a few feet away from the door. “Could those be it?” she thought. Being the germaphobe that she was, Chloe hopped on her right leg towards the hanger not wanting to get her left foot dirty. She quickly grabbed the keys and hopped back to the door. There were five different keys, but only one of them could lock this specific door, possibly. Without a moments hesitation Chloe chose at random and started picking at the door lock.
