2003 NOT Unlocking!?!?

[Goalkeeper]

Hey people,

I've got an 03 and for some reason, when I unlock the doors with the fob, the truck won't allow me in through the rear doors (that's what she said)...but seriously, the rear doors won't unlock nor will the rear hatch.

This is happening with both key fobs and although I can manually unlock the rear doors, I can't get the back open.

Its ont just the fob, when I hit the unlock buttons inside the front doors, the rear doors and the back hatch will still not unlock.

Any ideas?

Thanks!!
