Help - my 2009 4.6 started to emit tone sound all the time

Hi,
It happens whether engine is off or on. My regular mechanic doesn’t know what’s going on. It’s loudest near central stack where DVD player is. Did anyone experience something like this?

Here is the video:

Did you try disconnecting the battery for 30 mins to see if it resets?

Yep, tried to disconnect, waited whole night, on reconnect starts this tone sound immediately

That sounds a bit like the "key not in vehicle" warning tone you get when you close the door when the car is running and the key fob is not inside the car. If the car will not start unless you insert the fob into the dash slot, then I would look first at the wireless key fob receiver. Whatever circuit is driving the little warning speaker is probably toast, or the module (or both).

Yeah, all remotes stopped working more or less, that happened years ago the only way to start the car is to insert key fob into console. Changing batteries on fobs doesn't help so i guess it's something more serious. But this is another issue that i accepted to deal with and this was the case for years anyway.
