    Best stuff? The MB lock lube, which of course is NLA.

    EDIT: See post #30 below, the lube p/n 002-989-06-51-09 may be available again. Click here for Naperville pricing.


    See post #19 at this thread, the VW / Porche spray would be fine (likely identical to MB), but that is NLA as well.

    Next up is trying to source the Liqui-Moly spray from overseas via a group buy from helpful members across the pond.

    Dunno what other stuff would be recommended; the MB lube was a clear liquid in aerosol form, not dry graphite.

    Found this old post from Doc Booth recommending to avoid graphite or conductive lubes:

    Date: Wed, 20 Apr 2005 08:59:27 -0400
    From: Marshall Booth
    Subject: Re: MB Locks

    Whatever the MB stuff is (they're not saying) it isn't conductive so it
    won't cause problems with the alarm switches (like graphite based
    lubricants do). Works quite differently (at least lasted MUCH longer)
    than the silicone sprays I've tried.

    It's been discussed on this forum, and checked and double-checked. The stuff is NLA from MB.

    Though a few of us have a supply in our parts stashes....

    May want to try this "new" (updated) part number for availability, though: 002 989 06 51 09

    Re: OEM Key set for 94 E500

    When I tried to order 002 989 06 51 recently Gerry my dealer allowed me to place the order..... that was around 6 months ago now and still a no show. He told me to forget about it that it's likely to never come now.

    I am trying a local VW dealer to order their lock lube spray can today (if they are still available) From the pictures it looks like it could be the identical product as MB.

    I was able to place an order for one VW lock cylinder grease spray G052778A2. They said it might come back with a min order qty and they will let me know if that happens.

    BMD, you better keep that stuff locked up. There's not telling what these vultures around here will do.

    It seems like we are over-thinking this, but this is the 500E board so of course we are. Isn't something like this just fine from Masterlock. Doesn't Masterlock know a bit about locks?

    Someone on the Rolls Royce forums suggested this for my jammed lock cylinder. I've not used it yet.

    I guess over- engineering and over-thinking go hand in hand, and with the internet, we don't want anything but the BEST, hence this conversation about lock lubricant.
    Heck, this may be the beginning of yet another type of "oil thread"!

    I’ll take the bait... is WD40 no good? I’ve only used it on the Audi, as it spends the most time outside. Should I not use that method on cars I care more about?

    I've used this over a period of decades on all cars that I've owned, places I've rented, homes I've purchased. Although not design for locks or tumblers, never had an issue over all that time.
    Yes, I'm a cyclist so had it in my tool box.

    In the Dark Ages before I was able to obtain the MB lock juice, I used Tri-Flow for many years with great success. It's good stuff.

    I'm actually quite surprised that GSXR hasn't chimed in with a handy solution from his Uncle Kent.

    I picked up my can of VW lock cylinder lubricant this morning. It does look identical to the product in the pictures of this thread except for VW - not MB branding. £9.79 GBP Inc tax

    Let’s hope that your MB locks don’t reject being lubricated by a VAG product and fail on you prematurely.

    Joe, can you post a photo and part number for the VW can you picked up? This appeared to have been NLA in USA, I'm curious if it was temporary NLA, or if you scored some NOS leftovers.

    Yes no problem Dave I will do that when I get home in a few hours. They said it came in from Germany. It was AOK to order- I would say more are available indeed I might buy a couple more cans in case it does also go NLA with VW

    I cant see a manufacture date on the can - but it seems "fresh" stock. It is a white greasy lubricant and seems to work very nicely. Done the door lock, ignition tumbler and trunk lock on the S280 and the door + trunk lock on my w211 so far. The little fitting on the can is a squirter which fits into the keyhole. A couple squirts, work the key in and out a dozen times with a few more squirts as needed to get it 100% smooth then wipe off the smoo and your done.

    Re: What is the best lubricant for 124 lock cylinders?

    I think the reason I suspected G052778A2 was NLA is that ECS shows NLA... but someone would need to pester a VW dealer in USA to confirm:
    https://www.ecstuning.com/b-genuine-...g052778a2~por/

    Veedub's website shows a price, but as we know with MB, that doesn't necessarily confirm availability:
    https://parts.vw.com/p/Volkswagen__/...G052778A2.html

    If this lube is still commonly available, it's definitely what I'd recommend for any vintage MB's with steel keys. You could try it on KeylessGO but it might just make the fob slippery.

    Re: What is the best lubricant for 124 lock cylinders?

    I've been using this stuff on my fleet of 124s. So far so good, and it's a clear graphite-free formula similar to the Mercedes product:

    "Some lock lubricants, like graphite formulas, leave a dirty, hard-to-clean mess on locks, doors and equipment, but 3-in-One Lock Dry Lube’s clear formula dries quickly so that it doesn't attract dirt, which can clog up lock mechanisms. The quick-drying lubricant is safe for use on metal, wood and most plastic surfaces."

    You can get it at the Home Deathspot for $4 a can: https://www.homedepot.com/p/3-IN-ONE...0074/205864344

    They most definitely 100% can still get the tumbler lubricant. It came from Germany, three weeks after I ordered it.
