    Disco Td5 locks, help needed

    Good day All,
    Did a trip around Aus and after the trip my locks were newer the same. I've been struggling with the rear lock (door 5) for months. It does not want to push the little pin up to unlock the door. Sometimes it works some times I struggle for a couple of minutes.
    Now the drivers doors lock does not push up the 'pull' pin up at all. So I need to de-activate the alarm and then use my key to and turn so that the pin pops up.
    The left passenger lock also had trouble that is now fixed, the pin popped out but nothing happened when you pulled the door handle.
    Any way I've had the back door open and cleaned out all the dust, took the locks out and cleaned them to. Still same problem.
    How can I fix the lock problems in the disco??
    Thanks and Happy 4wdriving

    Hi
    My RH passenger door is lazy,but a press of the dash unlock button fixes it.
    Have you tried this????
    I havent been game enough to start pulling the door apart yet.

    <span style="color:blue">sounds like a case of lube and adjust......
    lube the linkages and makes sure they are adjusted correctly....
    the door lock solenoids do not have enough power to lock or unlock
    if they are not set up in the right position.....they need to rest in the centre
    of their travel distance....</span>

    I had a problem with my rear lock in Coober Pedy after a trip from the Flinders up to Oodnadatta and back down - I found it would not open.

    For a day or two before hand it would only unlock from the control on the dash.

    Full of dust...

    I good belt from the outside on the plastic handle managed to shake the dust free and get it open.. I then DROWNED it in CRC... basically flushed it through... No drama after that until a couple of months later - had similar symptoms - again gave it a big flush through and all is good again.


    Glad we fixed it at Coober Pedy..... for a while there it looked like I was climbing over tha back seat every time I wanted a beer 8O 8O 8O

    Had trouble all over the place with Defender door thingys, keyed, not remote, sprayed the bejabbers out of the lot of them with Inox or the dreaded wd40, shhh, don't tell. It may attract more dust, but made the locks work again, had a bugger of time getting the spray off the rest of the truck, but there you go.

    Cheers

    Good day guys,
    The centre unlock button does not unlock the back door, you can hear it go but nothing happens, will check out the driver door later today.

    The big question is, do I buy a new lock and linkages for the back door. I've had it open, even took the lock right out, cleande it and lubbed it. still same problem, new lock is $230 so if I can fix it otherwise it would be great.

    Thanks for all your help so far

    Happy mountaneering!!

    WD40 sprayed into the lock and flick the lock, by that i mean pull it then let it go so it returns sharply, this has happend to ours it is jammed inside and flicking the lock several times even banging it with your hand should loosen it up you can lock and unlock the car several times as well, i also took the panel off and sprayed liberally inside too.

    It worked for us, with luck it will work for you.

    I assumed, when I came across similar on the Defender, that it was a cumulative effect. A little bit of dust in the keyhole, and in each joint along the way to the unlocking mechanism adds up to problems opening the door. I found that I had to clean out not just the keyhole, but also every joint along the way, there are so many joins, and comparatively so much distance to travel. I guess that grit in the actuator motor gears would also contribute.

    Cheers
    Simon
