Locked files, how to unlock and prevent locking again?

Hi!

I tried everything to unlock files on Lion (even unchek "lock documents" in Time machine, BUT ins not that kind of lock that is making me crazy!!!

Most of my documents are locked WITH THE LOCKER!!!!!!

When I "Get Info" a file it appears like that:

The I Unlock and put my password when asked. The file appears like that.

As soon as I close the Get Info window, and open it again.... THE LOCKER IS CLOSED!!!!!

I can't stand that anymore!!!!! Could someone help me with that???

Thanks...

P.S. to make it clear in both ways the locked button is uncheck!
