I replaced the trunk lock on my 560 SL (86) because it couldn't be locked or unlocked with the master key, now I can't lock or unlock it either but ii must have left it on locked position when I put the new one. So I have a locked trunk and I cannot open it.
What can I do, help!

I have a non-destructive procedure that will unlock it. There are too many pictures involved to post here directly. Send me your direct email and I'll share what I know.
