I know there have been posts on trunk issues before, but when searching I find most relating to the cabs and not coupes.
Went to the store last night, grabbed a 12 pack of tea. Hit trunk button on key fob, trunk opened, placed tea in trunk. I drove 1 mile to my house, jumped out, hit the trunk button on key fob and nothing????
As I said to myself, "must be the battery going bad on key fob, I'll just use the inside button no prob". Wrong! Nothing there either, won't open. WTH (I don't curse so what some use fu*k in WTF I use heck lol. Just so you won't be asking what is WTH.
Anyway, no prior issues with trunk key fob or inside trunk release button. Looking back I "kinda" remember thinking to myself it took 1 or 2 seconds longer for the trunk to pop open than normal when at the store but maybe just 2nd guessing.
Only thing I do notice is that the light is not lighting on the trunk release button inside like it always does. Ok, fuse must be the issue, pop the hood, check that fuse, good, not blown. Looking at fuse diagram it notes other fuses in the trunk. Bad place if locked out of the trunk IMO.
Oh yeah, mechanical key does not open trunk, checked it on the doors and it works, thought I might have it in backwards or something but no. Almost broke it off trying to turn it so I stopped. Goes in but won't turn at all. I can push the trunk key area in with my finger as if it was going to open but nothing.
Got on the gas pretty good when going home so the tea could have I guess, smashed toward the back of the trunk and broke something?? Dunno.
So, if I don't get in the trunk before Winter the tea will explode in the cold. Not to mention if I get a flat before I get the trunk working again. Please help.
So I'm out there wiggling the mech key like some say online to do and it's not turning. Dag gone fingers are getting sore, been trying for 30 minutes.
Not sure which way the mech key is to go in since it slides in both ways. If you know, which way is the clip facing left or right to turn the key going by my pics?

I was lucky to open a frozen lock mechanism with the spare key, a can of lubricant and much patients. I held the tip of the key with needle nose pliers and carefully worked it in both directions.
I found debris today while working on the convetible top circuit (fixed YEA!!). There were tiny tie wrap trimmings and plastic particles collected near the latch hook.
There is a valley there to collect foriegn material. I sprayed it again with lube. I will open it some time soon and resurect on my spare time.
The original problem that you described sounds as though the vacuum line to the trunk lock is loose/ leaking / blocked.
I don't think that this original problem is directly related to the fact that your mechanical key won't operate the lock. The 'frozen' lock is common to many old CLKs like mine. I know exactly what you are describing as it gets sore on your fingers to wiggle that pathetic little stick of metal.
Do you have the owner's manual. According to Merc, to unlock - the key twists anticlockwise about to 10 o'clock and then the lock pushes in to open the trunk. The key is turned clockwise to the 3 o'clock position to re-lock.
If you never resolve the mechanical lock problem - make dam sure your fob batteries are good and make a note of the engine compartment stud to allow recharging of a flat battery via the engine compartment.
Still locked out of the trunk, sprayed lock with anti siege stuff earlier today, nothing.
Vac line may be the case I guess, my only question is could the tea sliding around in the trunk be the cause of the problem if it slammed into the back on launch? Or it's unrelated?
Also, battery is gd on key fob. Opens doors fine and I also tested it at Pep Boyz by aiming it at the battery key fob tester (if you know what I'm talking about) Test said it works fine.
I do have an owners manual and did look at it but the key will not turn at all be it 10 o'clock, 1 oclock or non o'clock lol. Every few hours I go back out to try to get in again. Probably going to drill the lock eventually if I can't get in and install one from from the junk yard. Don't know what else to do.
The thing that is freaking me out is, I never got locked out before. Just out the blue and the trunk won't open.
Can you or anyone explain that if the light I normally see on the inside switch is no longer on is because it only lights when the trunk pops open or is in the process of opening? What ever is going on, the fact that I no longer see the light on when I pull the switch is tied to the trunk not opening.
I WANT MY TEA OUT OF THE TRUNK LOL! My frustrated yell.
Thanks for your reply.

Something inside the trunk is highly unlikely to jam the lid.
If I remember correctly, the red light on the console switch is only on when the trunk is open.
There are threads on this forum describing how to get around this problem. Not sure of details but most methods require removal of the first aid kit tray from the rear shelf and popping the back seat catch.
Already tried the first aid kit way, couldn't get the seat unlatched. I guess I will try more this week.
Thanks

Good news! I was able to get the seats down to get in the trunk. First chance I had to try again since last time. Come to find out I was not pulling the seat cord hard enough. Was a little angry about not getting in and gave it a harder yank today and "pop" left side seat opened. Repeated the same on the right and "pop" it also opened. My Razzleberry tea is safely in my fridge. Crawled in trunk to look around. Thank God it's clean in there.
Soooooo- first thing was to fold up my floor mat and pull that through the seat opening so I could get to the fuse box to check the other trunk fuses that weren't under the hood. Bad news, all fuses are good.
What do I do now????????
Recap-
Key fob battery works fine.
Fuses are all good. ( trunk and hood )
Mech key won't work on trunk lock, sprayed it last week with penetration spray, etc. key won't turn at all.
I hear nothing when pushing the key fob. No air, no sucking, no click, nothing.
There is no green button in my trunk or on the trunk lid. I just went out and looked again. Anyone post a pic of exactly where it is.
Non the less I have a news update!!!!!!!!!!!!!!!!!!!!!
Wait for it.......
Wait for it.......
Wait for it........
Tahhdahhhh!!!!
I got the trunk open with all the advise in the thread. I turned the car lights on to see if anything green would show itself or light up.
I crawled back in through the seat to look for it. Nothing. I pulled back the carpet around the lights to look. Nothing. Plus I had not messed with my lights at all. Hmmmmmmmmm.
Pulled more carpet around the lock part, saw the wires, hose,etc.. Everything looked fine. But after more looking I noticed a small white springy kinda push pen thing that was a skew. I reached in the tight space and pushed it even so it was level. I heard a click and said to myself "was that it?" A pull of the trunk release up front and pooofff the trunk opened.
Now time to inspect (in the dark) the trunk lid. The little white lever switch, what ever you call it that when pushed in turns the trunk light on an off was not springing back when I pushed it in. I had to manually pull it back out. What the heck?, What what make that happen??
Well, after a few minutes of tinkering I concluded that the carpet was not sitting flush and was binding around the switch. Further inspection and also thinking back why or would would make the carpet be slightly off fitting? The only two recent times I have done anything in my trunk was change a flat several months ago, AND CHANGE MY TAG LIGHTS TO THE LED WHITES!!!! I had to pull the carpet down before to get to the tag light bulbs and didn't get it siting completely flush again so I am the one who caused my trunk not to open when a few weeks ago I put in new bulbs lol.
Carpet is flush, got it back under the trunk handle like it should have been before and it works like a charm again. Mechanical key still does not work but that for another time.
Thanks again for all the advise!
