Open the door from the outside and on the edge of the door there should be a red button with a slot for the tip of the key near the lock, turn this and this will de-activate the child lock on this door. Do this to the other door and the child lock will also be de-activated, to engage the child lock do the reverse of the above.
This is only on the back doors ok.

Special tool like Torx key. Use the ones that can be inserted into a size 10mm bolt socket. I think it's size T50.

was the car involved in any accident
is the body panels damaged??

lock catch is dirty. clean it with brake cleaner and then spay wd40

If it won't open from the inside, but opens from the outside, check the kids safety lock.

if it does not open from the outside either, chances are it has to be repaired by taking off carefully the door's internal plastic cover. That one is a tricky one...
