I am not tech savvy and an android user myself. A neighbor, older than myself showed up at my door with a set of keys. Thought it could be a roommates as it was found near where they park, it isn't. I didn't realize until after it has an airtag. I don't know what to do with that, guess I just assumed someone might show up looking for their lost item being pinned via the airtag. Nothing. Is is possible it my other neighbors and it's not showing the exact location as we're so close? I have tried to ask via showing up and ringing their ring doorbell, but they never answer. How accurate is the actual find my airtag thing? It makes noise, so I assume it isn't dead.
