Trunk Lock Problem
1986 560SL The outer area that the key goes in to came out. The trunk lock still worked.
But now I cant get the trunk open to fix it. When I unlock yhe door I cant hear the Trunk lock work. The Key when inserted in the trunk lock it rotates 180 degress. I can push it in but the trunk will not open. How do I get it open? Do I look for a Trunk lid and just Sawzall a hole in the lid? LOL Thanks Steve |

Close to it! You have to drill about a 1/4" hole at about the 5 o'clock position to the lock cyclinder and push in on the part the lock cylinder is supposed to push in on. When you're done then you have to replace the chrome strip you drilled the hole in to. If the latch itself is bad (which you'll find out after drilling the hole) THEN you can punch out a tail light so you can remove the fasteners for the striker on the body.

OK, looking at that image, it'd be more like the 3 or 4 o'clock position relative to the chrome button, then a rod (not wire, too weak, more like a brazing rod) is inserted into the hole, at such an angle it'll hit the lever on the latch that the lock would be pushing on. You're using this rod to do the job the lock cylinder would do. NORMALLY this would open it. Unless the latch itself is junk. If you need to knock out the lens, find out if one is cheaper, I don't think it matters as far as unscrewing the striker.
If you need to drill, I think you need to drill through the chrome piece and the body, but after you replace the chrome piece you won't see the hole. Be sure to drill slightly in towards the centerline of the car. The lock is vacuum actuated, no wire. I'd be more inclined to mess with the KEY in this rear lock cylinder than any other approach to the problem. You could luck out. If it opens, remove the bolts that hold the striker in palce IMMEDIATLY before it accidentally gets closed again! Gilly

Could it be the vacuum lineis broken Could I apply some Vacuum to it and maybe get it to release?
Where would I find a vacuum line diagram ? Thanks Steve |

Nope, the lock cylinder is doing the same thing the vacuum is, plus you say you can hear the servo operating (I thought you said that).
Vacuum diagram is in the trunk....Ha! Just kidding. Various sources, the MB manual on disc for example should have it, but again I don't think it'll help you at this point. Gilly

My W107 - 79 450SL - With 4.5 v8 - has been sitting since it broke while I went through 'meltdown' and NOW I want to open trunk and replace battery etc. to start 'resurrection'. Is there a way to connect under hood to charge the line to the trunk then turn the trunk key??

You might be able to jump/charge the battery from the large connector just behind the coolant reservoir under the hood. With engine running, you should have enough vacuum to get it open. The cable runs directly from the engine bay to the battery, with no fuses or any components, so charging from there would be easily doable.
Just a suggestion, Scott
