As said order from Renault, 10-14days for mine. For the blip fob (inc. immobilizer chip), I paid £70 (got blade cut elsewhere).
Then half hours labour (£40-50) for programming to car. Only garages I know do it are Renaults, but there is a guy on here who says he can do it (was posted in clio discussion).
I've said it a lot (and will keep saying it), ring around a few Renault dealers and get prices first, as my local 10 were charging all kinds of prices for exactly the same thing.
