Won't start

[Regisgrate]

I recently changed the battery on my megane ll and now it won't start. Does changing the battery affect the immobiliser in any way

[VroomVroomClonk]

It shouldn't do.
I've removed and refitted my battery several times and the only additional thing I've had to do is re-input the security code on the stereo.

If its a new battery it should start, a second hand one might not have enough power to crank it , and remember you need to put your foot on the brake or clutch and hold start button. LOL

Foot on brake, push button.... Nothing happens and it's a brand new battery. There's a woman posted with same problem

Give this a try...

Put card in slot (DO NOT press the brake or clutch) >>

Press and hold the start button until the ignition comes on, wait 30 seconds >>

Turn ignition off by pressing start button twice >>

Lock and unlock the car >>

Card in slot try to start car normally.



Cheers.

Thanks will give that a try

[joe12]

Well ?

[Regisgrate]

Still won't start. Could it be a faulty button or starter motor

Check that you are getting 12volts on the trigger wire at the starter motor solenoid when the start button is pressed.
