RENAULT will turn a first when they introduce a special 'credit card' key system for its new Renault Laguna II series.

If you're looking to pick up a new key fob, or repair one, you might wonder how long programming it takes and whether or not you can do it yourself.

I have a Renault espace MK4, the card key opens the doors but won't start the car. I've put a new battery in the key card but it has made no difference.
