Apple has said that the AirTag's BT has a 30 to 40 foot range, which is a bit shorter than I would have expected. BT is of course a radio frequency system, so if the AirTag is placed in a metal container the signal could be blocked as that would essentially be a Faraday cage. If the AirTag is near metal or behind or covered by other objects the signal could be adversely affected as well. And other radio frequency signals can also affect a BT signal. So if someone needs to locate a lost AirTag/item in a large house they might need to walk around a while to get within range.
