    Default 504 - Best lubricant for door lock mechanisms?

    Hi All,

    I used an all-purpose LM grease to lubricate my 504 door lock mechanisms last year and now they are starting to not work, especially when it it cold. I suspect the LM grease is just too sticky.

    Nothing specified in the Haynes book apart from "apply a little grease". Granted, I think the tin of grease I have is 20 years old, now that I think of it. Maybe time to throw it out.

    So, what is the best lubricant for door locking mechanisms (excluding the lock cyclinder of course)?

    Thanks in advance,
    Hugo

    Morning Hugo, In normal grease the lubricating ingredient is the oil which is in suspension in the carrier. The oil will attract dust and may dry out inside the door. Recently I had great success with Motorex 622 chainlube for bikes when wanting to free up some 405 doors. Left the trim on and just sprayed in as best I could. It seems to wick-in well, and I'd reckon other brands would be much the same.
    Hope dat helps; kelpiebat

    I have always used this product in the past for car door locks: It doesn't seem to get over everything else.....

    Don't it always seem to go that you don't know what you've got 'til it's gone............

    I used silicone spray on my 405 rear locks.

    Hi Hugo

    Inox is very effective for locks and I've had it endorsed by locksmiths

    Hi All,

    Interesting that there are so many alternatives that are being used! I'm going to try white lithium grease (recommended elsewhere) on one door and give Inox a go on the other door as a comparison and see how both are faring in a couple of years.

    Thanks for the advice.

    Cheers,
    Hugo

    Don't use it on the parts external to door and/or the strike plates.
    Passengers get very cranky removing it from their clothes/person.

    Drilube is best for this.
    The less one interacts with rude, ignorant, critical and argumentative members. The more peaceful life becomes.
