Bit of a Strange One... Remote Fob Blocked?

[J i m s t e r]

Couldn't open the car with the fob last night, had to use the key barrel under the handle. Had to start the car with the key in ignition. Got out, couldn't lock it with the fob either. Same story this morning.

Fob had a new battery couple of months ago and has been perfect, including all day away from the house yesterday. I can see the fob light flashing. Won't lock/unlock on the fob even when inside the car.

The strange thing is...

...Same story with the wife's B7 A4. Since last night, her's is doing the same thing. Both unlock and start on the physical key.

Gotta be interference from somewhere? Nothing changed in our house, don't recall anyone putting up a mast (5G! Terror!) on our close either!

Just wondeirng if anyone else has experienced the same?
