I am the OP. Let me explain the situation more in depth since I only had 300 characters to do so before. My husband had lost his car keys, so I gave him my set and I took the spare lock key and the spare ignition key. I needed to get some groceries and he was at work, so I just went. Before I got out of the car to go inside, I put the keys in my sweatshirt pocket and got out. I got my groceries and came back out to the car, and yes it was in the same spot. I reached in my pocket to pull out my keys and only the lock key was there. I unlocked the car and immediately searched both the front seats, under the seats, in the cracks between the seats and even the back seat. I looked under the car and in the ignition too. I retraced my steps in the store three times and then checked my car again. I asked the service desk if anyone turned in a loose key, but no one had. I called my husband but he couldn't leave to pick me up, so I walked 4 miles home. The walk itself wouldn't have been so horrible had I not broken my foot a few months ago; it still bothers me, and there weren't any sidewalks half the way, so I kept twisting my ankle in holes in the ground. After my husband came home from work, he took me back to the store with his keys and I drove home. It wasn't until a week or so later that I actually found the key in the passenger seat, close to where the back of the cushion and the seat of the cushion met. There is no way I could have missed it when I searched for it and I had driven it a handful of times between the incident and when I found it. It literally appeared out of thin air and it still baffles me.
