Central Locking Problem?

I've bought it second hand, and this problem was there from the first day that I bought it second hand. One guy told me that I need to buy a complete lock actuator because probably the problem is coming from there. But before I buying I need to be sure that the fault is coming from the actuator so that I don't buy a new one and the problem still persist.
