So we got our Laguna second hand from a non-Renault dealer a couple of years back. It has this silly keycard instead of a normal key, and after having it for a year it broke. We had to buy a replacement for over a hundred quid. The replacement then died 6 months later and we had to get another one. 9 months down the line the same thing has happened and when I went into the dealership today to have a grump they told me I'd have to pay for yet another key because the 12 month parts warranty was void a year after we bought the first replacement.
So, despite the fact that the keys they are supplying do not even last as long as the warranty they provide, they will not be giving us another and we'll have to pay for it ourselves.
I spoke to a very reasonable man in customer services who heard me out but said that because we bought from a non-Renault dealership, didn't have a Renault dealer do the servicing and weren't likely to buy another (well, can you blame us?!) he wasn't going to do anything about it and he'd leave us to pay for another ourselves (which we have no reason to expect to last more than a few months).
AIBU to be a bit and and
