Help Please..Passenger front Door wont lock

[leton1]

Hi, Just fitted a lock actuator to my passenger front door on my BMW X5 2001 and only now noticing that the door doesnt lock when i press the button on the fob or the locking button inside. all the other doors lock and unlock without any problems.

If i manually lock it from the inside then the fob wont open it.
Can anybody help me please with this problem.
Thanks in advance

Mine had the same prob, Central Locking system didn't work on it. well it turned out that some wire was unplugged when they took it apart.
