Nissan Altima: 2001 Altima alarm goes off for no reason and my doors keep coming unlocked

For the past two weeks when I get into my car and lock the doors they come
unlocked while i'm driving. In the morning my doors are unlocked when I know
I locked them the night before. I have not been using my remote starter. I
have been locking the doors manualy. For the past 4 days my car alarm goes
off for no reason. I push the button on my remote starter and the alarm does
not respond immediately. The alarm just goes off with no manipulation, while
I'm driving or in the middle of the night. What should I do? I thought maybe
it was the battery in my remote starter, but I took the battery out and the
alarm still acted crazy. Should I unhook something like the horn until I can
get it looked at? What do you suggest? thanks

Thanks. There are no new neighbors, and there is no sign of break-in or
attempted break-in. It may be electrical.
