A blind hole is one with only one opening. He suggests you just have to drive out a couple roll pins, doesn't sound like that big a deal. Those work almost exactly the same as the side cut key locks, take all the little wafers out making sure you keep them in order, clean each hole with whatever it takes, a needle file will probably help. Clean each wafer until it shines. Reassemble with plenty of lube, I didn't find Houdini to work well for that, I like just dry graphite but you might have to use something else if you have an alarm. Once you've got it all clean and reassembled if it doesn't work well you can use a file and sandpaper to shave down the outside of the wafers to get a perfect fit. Make sure you test with multiple keys, its easy to get a lock working with an old key so it won't with a new one. -Curt

Insert key, turn to unlock (CW) direction, push lock / tumbler toward rear of car and pull out. Easy peasy, takes me longer to get the tools out than to pop that lock / tumbler out. Washed it out well with brake cleaner, then with Houdini Lock Lube, no change. Lots of black juice ran out, I kept going until it was fairly clear, but nope. It looks like there is a pin at the end of the assembly that can be removed, which then allows a piece and a spring and then a cir-clip to come off, and then just maybe the tumbler will come out of its housing. There are two more pins inserted into blind holes, I guess I'd have to grind the housing off on the blind side to be able to drive those out, but I'm not sure what that would gain me unless my first guess about removing the tumbler is wrong. ------------- Max Charleston SC On Sat, Jan 19, 2019 at 7:07 AM Meade Dillon <dillonm...@gmail.com> wrote: I'm going to remove old tumbler, flush it out really well and lubricate, and see if that clears the problem. New thought; if re-key of the driver's side tumbler is not possible, perhaps I can swap the passenger side to driver's side. ------------- Max Charleston SC _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
