Mate, I still don't know what you mean by 'rather than a DIY fix'...the DIYs I'm talking about are video tutorials how to change the door mechanism using genuine replacement nissan parts, nothing to do with universal parts or some cheap half-the-job fix... The proper job, with the proper parts, just so there's no confusion... I'll link them if you like, cos I have the distinct impression that you think I mean something else, or you're looking at something else
P.S. If you change the lock barrel, Aren't you going to need both sides and ignition barrel too? What;s wrong with your lock barrel? I doubt you'll need to change that or that it cannot be somehow transplanted in the new door lock mech, but that's an assumption, I haven't tried.
If you could link the videos that would be great, thanks.
I do need the door lock barrel, as when I put the key in it, it just turns without locking/unlocking the door; i think, the internals are no good now. I can change the lock and leave the ignition, surely? Just means two different keys
