check the clamp sensor front and back door

SOURCE: power locks for rear doors and hatch not unlocking

you have two relays on the interior fuse block one for locking and one for unlocking. Swap them and see if the problem is now such that they will not lock. If so you have your answer.

A wrecking yard is your best bet. The odds of you getting one that is bad are astronomical. Are you sure your remote has fresh battery's? Also check your fuse going to that devise before buying another one. The second choice on where to find one is eBay. Of course they are usually higher then a wrecking yard. They get a lot of there parts for sale by going to the salvage yard them selves. I hope this helps and Good Luck, The Raz
