Central lock auto unlocks...

Hi.

My central lock starting acting up a while back, didn't bother me much since i rarely lock it .
Now i want to get it fixed, problem is that when i lock the car using key or my alarm to do it it will auto unlock again, so i have to lock it by holding the key in locked position a few seconds.
I guessed that the drivers door actuator was adjusted too low so it didn't get the right signal, tried moving it and no luck.
So i tried locking it from the boot, same fault, but when locking it from the passanger seat it staid locked .
What should i do next?

Well it works now ;)
I unplugged the A pillar contact to the passanger door, tested it, it would lock, ok so i plugged it back in at it works ;) So if problems comes back i will take a look at the passanger side.
