Unable to open trunk (boot)

The trunk on my 2005 SLK280 cannot be opened.

It seems, when I last closed it, an overcoat which I packed into it must be caught between the brackets in the locking mechanism.
When the unlock button is pressed on my fob key, you can hear the lock release and, within a second or so, a noise suggests the boot has relocked once more.
I tried the suggestion in the Owners Manual, to detach the 'Emergency Key" from the fob, insert it in trunk lock and turn it anticlockwise, whilst simultaneously pressing the boot release.
However, the trunk will not budge in any way.
I even tried to pull it open in the fraction of a second between the 'unlock/lock' noises to no avail.

Can any member here suggest another way to open the boot, please...?

Might be a bit risky, but try lowering the roof only until the boot opens. This causes the locking grab up and you should be able to clear it.
Best of luck.

Thank you for the suggestion. So, I did as you suggested: tried to lower the roof a fraction, etc., however, the message came up indicating the luggage cover was not in place.

Nevertheless, it somehow opened a few millimeters more that I'd been able to yesterday. Encouraged by this, both my wife and I tried a number of different ways with no success.

She then looked it up in a forum for Miata drivers (!) — why would she looked there I do not know — where she found someone with an identical problem.

From that forum:

"Pull very hard. Did the same thing a few years ago. Have someone hold the key turned, and YANK. The fabric of the jacket is stuck in the latch. Mine was a nice London Fog microfiber, also very hard to rip. It escaped with a grease stain a few very small, barely noticeable thread pull on the arm."

The next post said:
I just got the trunk open. Well, as I speculated, the jacket was indeed caught in the latch. But it wasn't just the jacket, it was the big nylon zipper that was caught!!! I pushed and pulled and turned the key back and forth and pushed and pulled some more ... after a while I could feel the trunk "unlocking" (a definite click and then I could pull the trunk up a little bit, like maybe a quarter of an inch ... so I pushed it down so it would click shut, then "unlocked it", pulled it up a smidge then back down, etc, etc, etc. :Ohno: Finally I just got really steamed and basically did a "squat lift" pulling on the trunk lid and, bam! it released and opened ...and there, still jammed firmly in the latch, was the zipper of my jacket. I pulled it out and there's a pretty good grease stain and a couple of teeth on the zipper are gnarled up .. but I tried it and the zipper still works and the trunk latch/lock works and everybody's happy!

And so, that appears to be the solution: do a "squat lift" with all the strength you can muster... and it opens just like the 'Miata-man' said...!!

I tested the Vario-roof afterwards and it's working as smooth as always. The SLK opens and locks just as before and the only damage is a strap of a sports bag, made of that indestructible material, is now destroyed.

Nevertheless, the solution is now on the SLKWorld Forum for others to see.

Thank you "duserslk" for your encouragement.
