E30 325i Sport Thiefproofing central locking issue

Post Wed Aug 11, 2021 9:32 am

Hi guys,

So yesterday I purchased my first E30 - I bought it off an elderly couple on my road. It has been SORN since 2015 and kept in a garage unlocked since then.
It has about 120k miles with an extremely comprehensive history. I towed it up the road to my house as the clutch master cylinder has gone. Upon getting it onto my drive, I went to lock the car, little did I know about the deadlock function of the car when you turn the key 90 degrees to lock it instead of 45 degrees.
I rotated the key 90 degrees and it initiated the thiefproofing function and disabled the central locking - completely locking the passenger door regardless of trying to pull the pin up or using the key to unlock it. I can get into the boot and the drivers door. And through the boot I was able to push the pin back to unlock the fuel cover. Basically I'm looking for some advice on how to reactivate the central locking and get the passenger door open. I don't really want to start savaging the door cards off etc cause the interior is absolutely mint.
I can here a relay clicking when I turn the key in the drivers door from 90 degrees up to 45 but it doesn't seem to do any unlock function on the rest of the car.
I'm not very technical minded and any advice would be greatly appreciated.
Thanks in advance,
Oscar
