95 BMW 525i door lock woes

[Mgzone96]

So I got myself a 95 bmw 525i few months back. And as of recently I noticed the central door locking system acts up. So I only have a key no remote and when I unlock the either passenger or driver door, it'll unlock the whole car like normal. But I've noticed that now when the cars off the key only unlocks the one door. But once the car is turned on I can lock and unlock all the doors at once like normal. I'll know when it's going to happen too cause when I open the door the cabin lights will be flicking on and off. So any ideas what the issue could be? Maybe the gm assumes one door is still open or something? I'm at a total loss

Any waring message in the check control? Door open?

No the car doesn't warn whether a door is open or not. I'll check the microswitches soon as I get a chance. I'm fairly new to these euro cars so I'm learning where everything is as I go.
