If you live in a snowly salys area this can happen especiallly this time
Get some lock de-icer (which is just rubbing alcohol) or use rubbing
alcohol and a syringe. Squirt some alcohol in there.
What you're trying to do here is wash out guck and salt.
Then, spray in some liquid graphite lubricant which is the MB
recommended lubricant for this lock. USE NOTHING ELSE.
Especially avoid WD40 whcih will work but make a bigger mess next
If you do this every falll it should never happen in winter again,
but, that lock probably hasn't been lubricated in decades, right?

Try turning it all the way... holding it that way and push down to unlock
This is the way to try to open the trunk without locking and unlocking the
car doors to open up the trunk. Otherwise, make sure the keyhold is in
horizontal position... lock the driver door and then unlock driver door
again and just push in the trunk button.
My car is a 1976 MB 240D.
If you insert the key into the lock of the trunk, depress the trunk
button and turn the key clockwise, you'll hear a 'click' and nothing
If you insert the key into the lock of the trunk, turn the key COUNTER
clockwise, and then depress the trunk button, you won't hear a click but
the trunk will open up (well, it will usually open on the first try. The
lock needs to be lubricated after 31 years).
Give it a shot.
Actually, that doesn't work with my '76 MB 240D.
Only if I turn it counter clockwise, and push it in does it work. But,
as I said in my original message, "the lock needs to be lubricated after
31 years" and maybe that's all the OPer (and I) need to do to get it to
work when turning it clockwise. I just haven't bothered to do that since
I've always turned it counter...
