Door lock 92 325i

When ever I turn my key to lock most of the times the locks will go back up to beimg unlocked, but then sometimes it will lock, is something wrong with my locking sytem?

More likely it's the microswitch in the door latch. It tells the central locking system if the door is closed or not. If the microswitch is bad, the system thinks it's not shut all the way and won't let the solenoid lock the door. You turn the key, it pulls the lock down, but as soon as you release it, the solenoid kicks it up again.

Yah thats what it does

Yes. This. Pelican should have the replacement microswitch, that's where I got mine.

Something else to check, the locking knob bar may have gotten shifted out of position. I don't remember if when mine bent if it would occasionally lock or not, but it's relatively easy to check, and you don't have to buy any replacement parts.
