How do i Program Renault scenic key?

If you have the code to disable the immobilizer, put it in then press the button to unlock the doors until you hear it click three times remove the key and point towards the receiver above rearview mirror and press button on key very quickly ( has to get three good signals) then key should work normally. You may have to try this a number of times but each time the immobilizer MUST have kicked in needing you to put in the code
