Been thinking about doing this on the 300SD as preventative maintence. My tumbler looks as though it has been messed with before and it makes me weary.

It works flawlessly every time but I KNOW how much of a punk those things can be to have to fix if they don't rotate.

I need a new ignition key anyway...mine is flunky and short (PO lost the rubber part).

Is a 81 300SD supposed to have a non-high security key for the ignition? Cause mine isn't...(doors are though)

If I replace this I will do it with the dealer accuired part...not random key.

My bug had a random key when I got it and it bugged the hell out of me. I bought a whole new set for the car.

Security or non? ANy ideas?

Non-security

My '83 300SD has non-security ignition and security door locks. Wish it were the other way around as I like to keep several door keys around in various places for "Doh" moments and that can get pricey at $23 a pop.

Okay thats exactly what I needed to know

Thanks!

I guess when I get some spare cash I'll snag up a tumbler and key setup from the dealer and put it in myself.

Also need to get a 2nd door key made up...

It works!

Thanks to this forum and the 124 Service Manual Library CD-ROM, I was able to make the necessary tool and remove the cylinder lock from our new-to-us 1987 300D. Our lock still works well but some PO had replaced it with a junkyard find and the keys didn't match, plus we had no spares. Now I can order a new cylinder keyed to the car's VIN and get the car one step closer to stock.

Also thanks to Ferdman, who provided the information allowing me to find the instructions on the CD-ROM. Wish that thing had a better index or a search function!

is it acceptable to drive with a bypassed ignition lock assembly?

is it acceptable to drive with a bypassed ignition lock assembly?

the ignition key in my '82 w123 (240d) failed to work. i took dieselgiant.com advice (thank you!!!) on grinding down the pin potruding into the steering column. regardless the key still did not work! i bypassed the system by removing the vacuum lines and plugging them before starting...
glowplugs don't work but a squirt of WD40 does it everytime... I just short connectors on starter ad it comes right up
and unplugging the vacuum lines to kill the car!

my question is will continued use in this state cause any damage to the electrical sys or otherwise???

thank you for any input!
john

Cold/winter starting will be difficult/impossible.
The charging system should NOT be functional with the switch in the off position.

that was my assumption too. i tested the voltage after a short run to the store and it read 13.5V!! the gas gauge cuts in and out and so does the temp gauge but all else seems to work...

ty whunter for all your efforts!
