I was washing my guest room windows and found a tiny, clear plastic wedge jammed deep into the sliding track from the outside.

I have seen this before. My neighbor had a sliding glass door. She felt that someone was coming in when she was not there. Her friend, a man was talking to me while he was trying to figure it out. It clicked and he found if he slipped some kind of thin blade under the door and lifted it the door could be opened. I don't know if the plastic wedge is the same trick. I hope it helps someone to stay safe.
