Reset of the megane oil change

Hello everyone, a week ago I changed the oil and filter to a megane of 2003 but I can't get the key to disappear. They told me a way, but it has not reset. Seeing if someone can throw me a cable

Layers that can serve you this never try in the megane but this test
the board button where to put the mileage in 0 keep it precise we are talking without contact a 5 second later without releasing the same button that you are advising to place the contact and do not release it for 10 second and ready it has the service light reset
