Bouncing locks - anyone found someone to fix?

[Norfolkandchance]

Our locks bounce / "machine gun" when we lock the doors.

I know that the fix is well documented on the internet - involving replacing the spring in the lock mechanism and the cocktail stick / nail "trick".
I've tried the trick and it only worked temporarily. The indy who looks after my wife's B class did a lot of teeth sucking when I talked about the spring. I think he's not that keen on replacing the whole mechanism but certainly isn't keen on the spring.

I wondered if there was anyone who had experience of having one fixed? .

Thanks

Thank for the reply. Was that £400 for supplying and fitting or just the parts?

Thanks

Hmmmmm, I had already tried the spraying in of lubricant, as per the video, and it didn't really work. however, having watched the video I applied loads and it has worked. So we'll see if it stays like that. Thanks
