Problems with my locking system

[Unit87]

Hi all. I was just wondering if anyone would know or have had this issue previously. I have a 2006 VZ wagon, I close my drivers door before I have even started the car and all doors lock. Does anyone know why this could be happening?

Drivers door actuator. It controls the rest, so if it is faulty it will lock all the doors as well as the drivers door.

Ok cool. I'll give that a go and hopefully it works. Thanks for your help.
