I have been fixing my trunk central locking device, and finally fixed it. It was a broken wire where the trunk opens and closes.

Now the open/arm/activator to the lock mechanism is unattached and when I activate the manually open buttons near the plate, nothing happens.

I can't open from behind the back seats, because there is only a tiny little hole for Skiing or long stuff, through the seats in the middle.

What can I do?
Thank you.
