I've had the same fault, the card will unlock the doors but, when inserted in the key port, states "Card not detected". So I'm now using the spare and hoping it wont pack up too! Pointless gadget, give me a key any day!
I've had the usual main problem with all these cars, the window regulator failing and the window being useless. It was replaced under warranty but then packed up a month or two later, just after the warranty had expired and of course the dealer refused to do anything about it stating "there's no guarantee on warranty work after the warranty's expired". Also the front drivers door pocket continually fills with water when it rains (I may just stop emptying it and pop a goldfish in there!).
I know these are problems experienced by lots of people but, when you try to bring this up with the dealer, they pretend you are an isolated problem and deny all knowledge of these widespread inherent faults.
What it would take is for a solicitor or law company to collate these issues from owners who've experienced these constant design faults and take forward a class action against Renault to make them acknowledge and rectify these issues and the disgraceful customer service that has followed as a result. This happened before with Renault over the Clio which had an inherent bonnet catch fault which they continually refused to admit, despite several crashes when it popped up as the cars were going along. Eventually a court action forced them to admit it and recall the cars for repairs. Audi similarly had faults with the TT (old style) cambelt failing before it's due replacement mileage, causing a very expensive repair. Again, Audi refused to admit to this until a class action was brought against them and they recalled the affected batch of cars. So it can be done if everyone pulls together! As a single voice people are easily dismissed but as a group, they're much harder to ignore! And the press love to report these things too!
I've owned my 2003 Megane since new and like the car but hate the problems!
So, if there's any lawyers out there willing to act on this, get in touch!
