Airpods lost, last known location was two days ago, have they been reset or am I just not in range?

Hello, I misplaced my airpods two days ago. I thought I left them in my car. On Find My app I can see that they were last at my apartment complex two days ago, and I can still see approximately where, however I am not in range to use the sound feature. Since I can still see the last known location, does that mean that they may still be there? Like, if they have been reset would I still be able to see that last known location or would it appear to be offline? Just trying to figure out if I should spend more time looking for them at my apartment or if they have been stolen.
