Airtag won’t connect and can’t reset it

Hello

I have an Airtag that needed a battery change, done that with a reset and it worked ok.

After a couple of days, the app can't locate it and it won't send any peep sound to find it.

I tried all options but it still can't be located.

I tried to do a hard reset and deleted the old one to have it set up as new.

Once I have deleted the old airbag and opened the battery to reset it, it can't be reset. No sounds came of the Airtag with the 5 times battery hard reset step. Now, no sounds are coming of the Airtag the indicates it's doing the hard reset and it can't be connected to the iPhone.

Tried all the steps mentioned:

• Resetting the network setting in the iPhone
• On and Off the Bluetooth and Wifi
• Delete all Bluetooth-connected devices
• Shutdown the iPhone to refresh it
• two-way verification
• location setting

nothing worked

Any suggestions?
