Airtag not working on lost ite

I have an apple airtag on my keys. I lost my keys and signed into "find my" to locate my keys. I could see my keys/airtag on the "find my" map and it showed that they were at a restaurant that I was at yesterday. I walked to the restaurant and long story short, they were not there. While I was in the restaurant tho it continued to show me that the airtag/keys were at the same place as me and allowed me to play the sound and everything (though it was too loud for me to hear it). I left the restaurant and walked down the block and weirdly it showed the keys/airtag moving with me. I checked my bag/pockets everything again but of course the keys were not with me. I then realized I should turn on lost mode so I did that. Then I kept walking and "find my" showed the keys were no longer continuing to walk with me. Now it is showing the keys/airtag as on the corner, a block from the restaurant, where I had walked. I assumed this was a weird glitch so I went back home and tried again and now it still shows them as on that corner but it won't let me play the sound and says "airtag not reachable" when I try to play the sound but the location continus to update and show that same corner location.

What is the point of an airtag if it doesn't even work when my item is lost!!! Is there anything I can do to make the sound/location work again?

An AirTag has no method by which to independently detect its location (it doesn't have GPS), or directly report/transmit its movements.

An AirTag is effectively little more than a "beacon" that broadcasts its unique identity using Bluetooth, this beacon signal being detected by other Apple devices such as your (or someone else's) iPhone when they are in close proximity to an Airtag.

When an iPhone detects an AirTag (which in ideal conditions will be within 10m/30' of the detecting device - or for AirTag2 and a recent model iPhone, potentially as much as 100m), the detecting iPhone will anonymously and securely report the detection of the AirTag's unique ID to Apple's back-end servers, along with the location of the iPhone. As the AirTag will be within a short distance of the detecting device (for which the location is known), the location of the AirTag can be inferred to be within a small radius with high confidence.

As such, unless in proximity of an Apple device participating within Apple's Find My network, your AirTag's location cannot be reliably detected or reported. When detected, the reported position will be at that point in time - and will not necessarily update in real time. Quoted detection ranges are in ideal conditions; any objects between the AirTag and detecting device will attenuate the Bluetooth signal - and in so doing will reduce the effective signal-detection range.

an airtag have no location ability on it's own, an airtags only means of communication is bluetooth so about 30meters range

if an iphone with an active internet connection and bluetooth enabled is within bluetooth range of the airtag, the airtag will trigger the iphone to send the iphones gps location across the internet using the internet connection of the iphone and the across the internet location would be the find my app in your iphone

if no iphone with an active internet connection and bluetooth enabled is within range then your airtag is dead in the water.
