Door Lock Problem

Help dont know where to post question
2004 chev cavalier doors locks jammed. Doors wont open. the back doors. How can I fix it

First of all, please learn some English sentence structure or at least re-read what you've typed. That clearly doesn't make a hell of a lot of sense.

Your doors are jammed. ok.

Is it the key lock thats jammed, the actual actuator inside the door ( power locks) or the door just won't open at all from the inside or outside?

But your back doors are functioning as normal?
