    Help! 504 door won't open.

    The other night my passenger locked the front left door, everything normal. When we returned to the car I unlocked the door from inside, but the can't be opened by either of the handles, inside or outside. It seems like something is disconnected or broken, because there isn't enough weight on the handles when you pull on them.

    I don't think it's possible to remove the door trim without opening the door, to have a look inside.

    Can anyone help? Any suggestions what might have happened? More importantly, how can I get the door open to fix it?

    Get a "slim Jim" and open it the way thieves do? Towing companies and locksmiths usually have these devices.

    Sounds like the rod connecting the inner handle has come loose, prolly because those little plastic securing things have broken at the lock mechanism end.

    But If does not open from the outside?

    Then maybe the mechanism out side the door has broken? The actual thing that locks the door to the car frame? That happened to me once so i had to replace the outside mechanism.

    If this was okay u should be able to open the door with the outside handle.

    As for opening, as mike says some sort of rod down the inside of the door.

    Best of luck.

    On my wagon (which actually has different lock mechanisms from the sedan...) the problem was that the spring that activates the unlocking aspect of the setup had come adrift.

    You're right, you can't take the trim off with the door shut... or not easily. I did it, just prised the top open and worked away at prodding here and there with a screwdriver until it actually worked.

    It has happened before, and I found that lubricating the lock worked wonders. That was all that I did with that one and it's still good.

    Now I have a worse problem... a rear door has done the same thing on the wagon I have to get registered this week!

    So I'm desperate for an answer on this myself, because this one has a really good set of door trims and they're harder to get off in the back with the door shut than the front. Moreover, you can't get lubricant in there as you can with a front door, the lock is nowhere near the lock snib hole and away from the window that winds down.

    I'm going to take the car to Dr Doorhandle, a local lady (yes) who specialises in doors, just to see if she can open the door. Once the door's open I should be able to fix it, I have a wreck here to get the necessary bits off. If I have success, I'll let you know.

    You have a spare?

    Well what's stopping you taking the lock out and seeing how it works?

    Just look to see what moves when you unlock it, then prevent that moving and see what happens...

    You have to make the piece that moves do so to allow the mechanism to engage, you should be able to do that yourself once you can see what's happening in the one out of the car.

    I know this sounds ridiculous, but have you tried working the internal lock knob up and down a few times. Seem to remember it working for me eventually on a 504 with these sort of symptoms. It was a fair while back but I have a vague memory that the screws securing the lock in place may have worked a little loose and that the "jiggling" eventually somehow got everything into the right alignment.

    Cheers

    Naturally enough, Rod, seeing I was committed to getting into and out of my car several times the other week, I tried this many times.

    To no avail.

    Like I said, that spring was off, so nothing short of getting into the door and operating the lock somehow was going to work.

    As Ray said, you have to make sure that everything is well lubricated, and then tapping the door or jiggling things may put things back in place, in order for you to open it. Personally I recommend tapping the door adjacent to the mechanism rather than jiggling things. This only works, however, if the spring is still in place and only lack of lubicant is seizing things.

    If the spring has actually fallen off, you'll probably have to remove the outer door handle, like I did to a friend's 504 recently, in order to push things into the right place. Since one of the nuts that hold the handle is on the inside, I had to drill it out from the outside (not nice).

    On my friend's car we fitted a new stronger spring to the mechanism and lubricated it well. I've never felt a 504 door which works as well as his does now.

    Good tip there, Dave... I might well try that with this rear door I have here that won't listen to reason... thanks.

    Seeing as I picked up a couple of extra doorhandles yesterday, I guess I can cop the loss of one of those. And you never know, I might be able to find a broken one I can replace the bolt from...

    Job's done!

    Aided, I guess, by the fact that I knew what I was looking at (at least to some degree) because I had a latch I got from the car at Dubbo yesterday... fortunately it was the same type of catch, though the wagon and sedan are still different!

    Anyway, what I did once I had the handle off (drilled straight in and off it came! Someone held the handle up for me, of course...), and after a bit of mucking around looking at what was moving etc, I got a big screwdriver and put it against the piece of short 'rod' that comes through the door inner skin to be moved by the latch operation.

    Gave that a whack with a hammer, I'm sure the biggest problem was that it handn't moved in an awful long time, though the lock wasn't unlocking the door all the same.

    I sprayed through the door handle hole with a swag of fish oil spray, so it's now lubricated, and after I got the door open I got the trim off, more or less just tried the catch a few more times, bolted the another handle onto the door and put it all back together.

    Fine... done... great feeling. But Dave, I hadn't yet got to thinking of drilling out that stud... thanks for that. I might have in the end, but so far I hadn't dreamed of coming in that way...

    I tried jiggling and bumping, that didn't work. Sounds like drilling out that stud is the way to go... I didn't think of that either!

    John, if you can put your hands on a spray can of some kind of lubricant that has one of those pieces of tube coming from the squirter, put a bend into the tube and screw out the lock snib.

    Put the spray tube down through there and point in the direction of the latch and see if you can do any good...

    Maybe this should be in the common faults area?

    Seems like good advice for everyone?

    John,

    Before I drill out the handle stud, I usually try lifting the handle and squirting copius amounts of WD40 in the direction of the mechanism (i.e. towards the back of the door), then after a little while I give the door a few good hard taps just behind the keyhole. This often gets things back into the right position.

    I've only had the one case where I had to resort to drilling, and that was because the internal spring had fallen off.

    I did as Dave said this morning, squirted lots of WD40 at the mechanism, thru the door handle, then jiggled and thumped, but it didn't work. I spoke to Dr Doorhandle again, she said that since there was another car she could look at she'd have the door open in no time. So when she arrived, she climbed into the front passenger seat from the driver's side, locked and unlocked the door (with the knob) a couple of times and...

    opened the door!

    So I felt a bit stupid! One hour before I still couldn't get it open. Anyway, Dr Doorhandle had a look at the works, said everything looked fine, gave it some more lube, and charged me a minimal fee.

    Moral of the story: keep those mechanisms lubricated. I think from now on I will regularly squirt some WD40 or similar onto the mechanism. This is easy to do, at least on cars with lift-up type door handles: using a can of lube with a plastic tube sticking out of the nozzle, raise the handle, and there is a little square slot through which the plastic tube can be pointed. Give it a good dose. My driver's door handle was a bit stiff and it only opened at the top of the lift; this was immediately improved by doing the above.

    There are problems, as I see it, with all types of lubricants here.

    Dust does get into the doors, so normal oils are prone to getting all glugged up. WD40 and its stablemates dry out very quickly.

    I've been trying spray cans of fish oil on a lot of stuff, but I don't know if it might have some unique problems too.

    At least regular oil or fishoil in the door is going to reduce the prospects of rusting...

    Well there is the smell, of course.

    Attacks from passing pelicans? The crocodile threat when parking in N Q?

    Having to explain to passengers who are continually saying "I'm sorry! I must have something on my shoe?"

    Being questioned about Patagonian Tooth Fish by members of the Fisheries and wildlife service? wink

    You can get deodorised fish oil... the stuff I use isn't too bad at all, and it goes away after a very short time.

    And it's only $2.99 a (big) can from Super Cheap Auto...

    Oh, yes, I also discovered it's not bad as a penetrating oil. But nowhere as good as Goanna Oil.

    Next time I'm out west of Charters Towers I'll see what I can do, Ray. Expect a long, thin packet. I'm guessing you'll know how to process them?

    Some of the problems experienced sound familiar.....
    The back doors on the 604 have always been a bit hard to open. One will only open from inside no matter hoe hard you try, and one will open from outside of you lift the handle REALLY hard and jiggle the door. I will try WD40 and see what happens.

    Sagging door pins, and maladjusted lock strikers are well worth checking out too if you have general door opening and closing problems. They can make it hard to open doors, as well as to close them.

    Nobody ever seems to put "door maintenance" in the manuals or service schedules.

    Maybe a biennial sequence of:

    remove trim
    lubricate locking and opening mechanisms
    check and replace hinge pins if necessary
    remove anything likely to clog drain holes
    check and replace door rubber if necessary
    adjust striker plates

    would help.

    Probably the handle is broken. Diecast rubbish... they frequently break...
