The Car Key is an item in Clock Tower: The First Fear. It is found in the crate in the garage of the Barrows Mansion. It can be used to start the engine of the nearby car. If Anne, Laura Harrington, and Lotte are all dead at the time, Jennifer Simpson will leave immediately. However, if one of them is still alive, she will refuse to leave without her friends at first, having to be prompted three times before she will finally give in. The former will result in Ending G, and the latter, in Ending H; both are bad endings.
