Help! My back doors wont unlock!!

Please does anyone know what to do first one of the back passenger doors wouldnt work, now tonight the other wont unlock from inside either anyone know what?

Hi
I had a real sweat with my rear doors !
I decided to change the torx bolts on the door locks because of their rusted
heads.Anyway the new bolts being 1-2 mm longer resulted in both doors not
opening again!!!!! (BURK ) Anyway down at LR they were pretty fair,and gave
me one lock on garantie,the other i paid for!! I had damaged both locks,hard to believe ,but true. The point is they said there were alot of problems with door locks on freelys.
Wish you luck
Peter
