Reconnecting trunk to Central Locking

Hello fellow BMW fans!

My younger brother disconnected the trunk of my 1997 523i from the central locking system by using the key and turning it completely to the right and now I can't figure out how to reconnect the trunk to the central locking system. I've tried all sorts of things with the key and I know there is nothing wrong with wiring or parts.

The user's manual only shows you how to disconnect the trunk from the central locking system but does not show how to reconnect it.

I'm sure it is a simple fix. Any advice would be most appreciated! Thank you!

Turn it all the way to the left. Hit the 90 mark (parallel to the ground). That should do the trick.

To keep the trunk connected to central locking...just keep the trunk lock cylinder vertical ( | ).

It is simple as you said. If you keep the trunk lock cylinder horizontal ( -- )...then the trunk is in valet mode & not connected to central locking and cancels the interior trunk release switch. See SECURE SEPARATELY from owners manual below:






{The interior trunk release WILL NOT WORK when trunk is separated...aka in valet mode}

Thank you, both of you. However, the first answer only opens the trunk manually and does not seem to re-connect it to central locking.

As for the second answer, my lock is always in vertical mode but still (since whatever my brother did) does not re-connect to the central locking system.

I'm thinking about disconnecting the battery and then reconnecting it. Maybe that will reset the system?

Thanks for the tips. It is in vertical mode all the time. I tried disconnecting the battery and connecting it again - that didn't work either.

The trunk mechanism is working fine. The other guy told me to turn the key all the way to the left, parallel to the ground, but that only unlocks the trunk manually.

Any more advice would be appreciated! It's a real hassle at the moment. Then again, old cars didn't even have central locking...

You may have a failed trunk actuator.

Does the actuator make noise when you try the remote function?

The remote function works normally when I use the "trunk unlock" button on the remote. But when I use the "unlock car" button, it does not trigger the trunk (and there is no sound). It was working fine before my brother opened it manually.

I'm slightly confused by the statement above...may I ask just a slight clarification?

Normal operation is...if the trunk lock cylinder is in the vertical position ( | )...it should be connected to central locking. Thus, when you unlock or lock the vehicle...the trunk is in the same mode as the doors.

But when you unlock the doors (manually or with the remote key)...the trunk is accessible & unlocked...but to "OPEN" the trunk, you still have to press the trunk lock cylinder inward...or press the trunk UNLOCK button on the remote.

Are you saying it doesn't operate this way?

Just a quick guess... frayed wire to the lock.

EDIT: Or... since I don't know how the lock and the electrics interact... a malfunctioning lock. Someone should find the WDS diagram. Wink, wink, nudge, nudge...

Yes, that is normal operation and it is what is not happening with our car. It is in the vertical position but not connected to the central locking.

As for the trunk unlock, the button on my remote that unlocks the trunk also opens it (I do not need to pull the trunk handle). This has always been the case with our car.

I need to take it to an auto electrician because the airbag warning light is on most of the time for some reason, so I'll get them to have a look.

Thank you for your time!
