Trunk won't open

Ok, went to the store over the weekend in the 88SL the trunk worked fine. Put some packages in there and head for home. Now, the trunk wont open. The locking system seems to be working fine on the doors. The problem is the trunk button will push in however it will not unlock. Any suggestions? Is there another way to get into the trunk? Normally you hear the release engage but now nothing happens. You can push the lock but its not releasing. Your help is greatly appreciated.

Rear Trunk Lock

In these odd situations, I found it easier to go visit the MB dealership body shop or other shops that are familiar with MBs and just ask a technician what is the trick to opening the truck. As you know, the vacuum lock mechanism apparently has failed, but there is generally an easy fix. Don't get out the crow bar just yet! Good Luck!

Unhappy Locked trunk

Sorry to hear about this. I just went through the same frustration.

I had suggestions from driving a small screw driver into lock and destroying it and it will open, also can drill hole through chrome peice and insert welding rod and open, also go to lock smith and he could not get it open, also go to MBZ dealer and they will drill out old lock and replace with new keyed lock to match others for $200 plus. Not liking any of the above I started thinking like I did in many days ago when I was a Millwright for a living.

I went under the trunk and measured from appox. the center of the spare tire hold down bolt out to about 12 inches and drew a circle. I then drilled a starter hole and used my jigsaw to cut a 12" diameter hole in trunk bottom. I was able to push the spare tire up and out of the way enough to get to the lock and open the trunk. Worked on lock and now it is working. Now I am not sure if I want to repair the bottom of trunk incase it happens again. Maybe leave it for a oversized drain hole.

This may all depend on what are in your packages as well.

Hope it all works out for you.

Well, went to the MB dealer today my options was limited. Of course the obvious solution drill the lock and order the matching new key. I don't want to go that route yet. Still seeking options.

Well, the wife finally got a chance to drive her car. So, we played with the locks. With the car running, I had her pressing the door lock open and close while I was working the trunk lock. After about 30 tries it happened, the trunk opened. Now we can fix the problem. Now I can relax. Thanks for all the help and wisdom.
