driver door stuck shut / lock jammed

My door is stuck shut. The locks won't work, it seems like it's jammed. The dealership wants like $300 to fix it. Does anyone know how to fix this, or at least how I can get the door panel off with the door shut?

Had this prob on my '02 SVT (in cold weather)
However, my locks still worked, but the outside door handle would pull out and stay out...
Needs to be lubed (plastic and rod linkage right behind the handle)
Pop off the inner mirror pod (just clips), and remove the torx screws along the bottom and outter edge of door skin...pop off the cover on the inner handle (the one for closing the door) and remove the bolts inside th handle...lift the whole skin straight up, as it is wedged into the lower sill...
Hope this helps

Thanks vintweed! This just happened to me today...nothing would open from the outside so I had to open the hatch and climb through to open it from the inside...pretty embarrasing. Thanks for the help!

yea i had something smililar happen to my rear driver door on my 00 se. the outside handle just flopped in and out like it was disconnected and the inside handle felt like the child lock was on. so i took the inside of the door off (which sucks if the door isn't open) and some how magicly the door opened from the inside and i didn't do anything, then i was messing with the locking mechanism and randomly the outside handle worked. Im not sure how i fixed the door but it works now
