3volt Lithium coin battery (CR1220) on my '96 clio it has 2 thin 3 v stacked on top each other
The key is in 2 halfs and slides apart with a slight pressure in opposite directions
HI, I have a clio 172, i have recently had that problem with my car, what would be worth doing is actually changing the battery in the key fob, if the battery is week it will not recognise the key and therefore not start. It will crank but not fully start, I changed my battery in the key fob and started first time after!
I had this problem on my clio 172, it's just the battery in the key fob may need replacing if the engine will turn over but just not start? works everytime for me now!
the fob may need recoding to the vehicle, if you still have the second fob then point and operate this fob at the receiver (by the interior mirror) and operate the faulty fob at the same time, this should bring the second fob back into sinc. robb

this happened on my 1999 clio and found it was the key, i used the spare one and it worked straight away, if not then you have to ring Renault for them to sort it.
You need 2016 batteries (3Volt)

remove screw from keyfob near stem, then prise apart. If the fob is not working check the solder joints around the buttons. Hope this helps.
