Pioneer XV-DV252 Remote control AXD7440 ,no battery include

ladies and gentlemen it says to you I have this unit pioneer amplifier which is pioneer vsx 1131 I believe and this is original one that came with it and as you can see there it doesn't work no matter what I do it's not responding so I tried to look up and just like anybody else and google it and see what the problem is I even try to open it which is a bad idea but it didn't help so here's what I did to fix it keep the on button that's it that will bring you to the system menu and press ENTER and once you're here you have to navigate to miscellaneous which is the last option down there by using this the arrow zone on the unit it should be like this so using the up and down arrows select until you get to miscellaneous press Enter and go down to remote ID enter and then you will see three different options I got three different IDs you can change the remote ID to avoid interference only i
