Keyless Entry just stopped working

[bdavis1369]

I noticed the other day that my keyess entry just stopped working. Both remotes are not working so I know it's not just a bad remote. Right about the same time, I also noticed that all of my radio stations presets and settings had returned to flat, like the battery had been disconnected or died, but it didnt. I have tried to reprogram the remotes using the "key to position 1 and back 5 times then hold unlock while pushing lock 3 times" blah blah blah, but it wont even respond. Anyone have any ideas? Thanks in advance. FYI 2002 X5 3.0
