Drivers door lock fault (advice please)

I have had fobs coded to car (previous thread) the door lock would lock with fob but not unlock and the just died completely Could not lock with fob or keys!!! I know this has been covered many times and I have read old posts. I have replaced door lock. It now locks with fob no locking again, but does lock unlock with key. I was rushing to do it due to rain and been late for work but I have noticed that where the barrel goes into the lock it fits two ways by spinning plastic bit in lock 180 degrees. If this is so and I have fitted it wrong would this stop lock opening with fob as it misaligned. It does make sound (click) like its trying to unlock??

Answer fitted correctly c@@p lock. Taken it back and got my money back!!

Having a nightmare with these locks another lock today and same problem!! So I'm wondering electric fault?? Does anybody know wiring on plug for locks??
IE what number pin is live for unlock,lock,deadlock ?? So I can check this its either that or another dud lock????
