Good site for keycard repair

Anyone having issues with the keycard not opening doors or intermittent keycard working problem there is a way to fix this issue.

rather than pay £160 for a new one at your local renault dealer, there is a company called http://www.keyrepair.co.uk who solder the buttons back on, and fix any dry joints etc which gives you a 100% working keycard for £25 with a fairly quick turn around from what i've heard.
You can also purchase a new case which is probably better as the old one gets cut off during the repair.They can glue these back together but it's worth the extra tenner to have a new case.

I didn't use that company but my friend did. He was very happy with them. They fixed his card quickly and it works well since then.
