Undo the plastic casing around the ignition.
Its only around 4 screws easy.
look around the barrel where you insert the key, there should be a black plastic ring around 3 inches down the barrel this is the key reader its not fixed so twist gently and slide up the barrel as close to the key as the wires attached will allow.
then try starting, if it works then the transmitter in the key is most likely deteriorated . if it works its only a quick fix and could deteriorate in time.
a new key and coded from Renault is £300 with no guarantee that its not a different fault so look at buying one of ebay and get that paired to the immobiliser.
there is another way of bypassing the immobiliser by removing a ball bearing in the fuel pump a bit more complex.

To check to see if the immobiliser is causing the car not to start there is a small red LED in the centre of the instrument panel normally with the Car locked the LED light should be flashing everyone second this is normal behaviour, Now with the key in the ignition and ignition on normally the led light will go out giving the immobiliser authorisation to start if in this procedure the LED light is flashing rapidly then there is a problem with most likely the key if you have a second key I suggest you test it,

if the red light flashes on the dash its going to be an immobiliser fault, normally it is the key that is at fault, the keys are pricey about £80 plus programmimg, but you can manually override the immobiliser on the early scenics, just pop into your renault dealer and ask for your immobilser code, normally charge a tenner or so, and ask if someone can show you how to put it in.

its a renault ,what else do you expect ??hope you got a nice discount to compensate you for a dealer only repair car.these cars are sold under false pretences as they are a millstone around your neck with their electrics and encrypted software.the repair is to change the facia behind the radio as its a one piece electrical circuit and if you unplug it the famous renault immobiliser cuts in so its dealer only .

R reg Megane Scenic non start


Hi

Well, no noid signal and no spark says to me that the crank sensor is at fault.

Does the check engine light come on when you turn on the igntion? If not then the ECU is not waking up.
