i have removed the rear seats one opens quiet easly but the other seems to be locked and i can not find a catch to open the seat from a folded position any helpi would be very grateful

What do u mean by remove? u actually want to takeout the front seats completely?

Well, I have the same car, never tried to do that. I am sure they are locked to protect those in the front seats from accidents. I think you should take it to a professional if you really want to remove those seats.
