Rob36 Posted September 1, 2021 Share Posted September 1, 2021 Hi all. I’ve got an issue with the door lock barrel on my cavalier coupe. The lock, although turning as it should , has stopped locking/unlocking the door. Reason being the plastic arm that’s at the back attached to the back of the lock is slipping on the spindle. Is it buggered, or has anyone encountered the same issue and fixed it? I can’t see anything immediately wrong looking at it other that the plastic arm doesn’t turn when the key does and slips. Any advice would be appreciated. I’d prefer not to have yet another key really, and I can’t see any locks available online at the moment. (It’s passenger side) Quote Link to comment Share on other sites More sharing options...
paulmanta Posted September 1, 2021 Share Posted September 1, 2021 Fixable, but if it's not you can put any combination of tumblers in. A door lock so you can keep the key. I've done tons and could sort it out for you if you want. Quote Link to comment Share on other sites More sharing options...
Rob36 Posted September 1, 2021 Author Share Posted September 1, 2021 Thanks for the reply Paul. Appreciated! Here’s a pic of the barrel. I’m assuming the plastic lever will have to be removed to perform a bit of surgery? It looks fairly brittle. Looks to me like there should be a part of the mechanism that slots into the plastic bit creating the turn when the key is twisted,but that has either slipped backwards or broken off? Any points on how to tackle fixing it would be much appreciated mate! https://www.dropbox.com/s/ezoarxpdnx7stgu/7FEACFCC-C649-49D5-AFFE-9C111564447A.jpeg?dl=0 Quote Link to comment Share on other sites More sharing options...
Mickfrad Posted September 2, 2021 Share Posted September 2, 2021 Little bit fiddly to get apart, couple of small screwdrivers to squeeze the split ring on the back. Quote Link to comment Share on other sites More sharing options...
Rob36 Posted September 2, 2021 Author Share Posted September 2, 2021 Hi Mick. Thanks for the reply. Have yu uploaded a pic there? - It says theres content on your post, but I cant see it unfortunately. I think Ill pop into a local locksmith later on to see if they can do anything with it. Failing that try and source a used barrel that I can salvage bits from... Quote Link to comment Share on other sites More sharing options...

Rob36 Posted September 2, 2021 Author Share Posted September 2, 2021 Ah ok bud, fair enough. Anyway, long and short is a new lock is needed. Took it to a locksmith who set about it with a too-big screwdriver and snapped a couple of the lugs off the end of the plastic bit before I stopped him and told him not to bother. I managed to remove the plastic bit at home, which revealed a metal shim that slots into the plastic part from the inner barrel has snapped off, so that was the problem. I’m now in the hunt for a new barrel if anyone has one? Even one without a key as I’ll be swapping the bits over… Quote Link to comment Share on other sites More sharing options...
paulmanta Posted September 2, 2021 Share Posted September 2, 2021 Send it to me with a key and I can sort it. You Pay post but that's all. Pm for address. P 3 Quote Link to comment Share on other sites More sharing options...
Rob36 Posted September 2, 2021 Author Share Posted September 2, 2021 That’s a kind offer Paul! I’m fairly sure donor parts will be needed now though? Having taken the thing apart now and seen the issue, I’m pretty certain it’ll need a new inner barrel, and a new plastic rear arm thing, since the locksmith pretty much wrecked it, and I also contributed a bit getting it off at home… I’ll have to put it back on for a week now though as we’re going to mid Wales for a week and I’ll be taking the car I think… Quote Link to comment Share on other sites More sharing options...

Christianjhonson Posted June 11 Share Posted June 11 It sounds like the plastic part attached to the back of the lock may be worn out or broken, causing it to slip when you try to lock or unlock the door. This can usually be fixed by replacing the worn parts or adjusting the mechanism. A locksmith can check the lock and suggest how to fix it without needing a new key.
