Can neighbors remote impact your system functions?

I've been wondering if i am the only one with this problem - or even if it's the cause of the problem at all. Almost daily I find my amp in mute mode, or on a different input than I left it. In addition, my volume jumps a few notches sometimes for no apparent reason while listening . My only explanation is that my neighbors remote input is somehow finding my amp and interpreting it as a command. Neighbor is upstairs in a frame/stucco building, not able to involve them in a test for personal reasons. Anyone have a similar issue ever?
