Jeep Liberty SEEMS HAUNTED?!?!?!?!?

We have a 2005 Jeep Liberty and has been running fine. Yesterday went
shopping, all kind of short trips. Came home and parked in the
garage, went to leave last night and just clicked and wouldn't start.
So we took the other vehicle. Today we went to see if it would start
and as soon as we opened the hood and the door, the CD player sounded
like it was constantly trying to reject a CD. And it also sounded
like it was trying to unlock the rear gate. When we tried to start
it, it just clicked again but the rear hatch popped open. Wouldn't
start but every time we turned the key it would just pop the hatch
open and the rear lock would start popping. The doors wouldn't unlock
or lock with the key either.

Tried another key (moving this one waaaay far away in case the key was
messed up) but got the same results.

Weirdest thing we have ever seen with a vehicle, was thinking just
battery but it's fairly new and completely clean. Now we're thinking
something major electrical.

Any suggestions???

Well, after a couple trips from a AAA rep turns out that the battery
was toast... swapped it out and everything's fine.
