Hello and good day to you.
What year car, make and model is this?
Let me know and I'll try to assist you.
not sure of year but its a 03 plate
renault megane 180g/km
not sure of year but its on a 03 plate,its a Renault megane
as an 03 could be an early or later model, is the key a key with a button to press to lock and unlock the car? Or is it a card type key? Or do you have the registration of the car?
Let me know,
its the card type reg is bd03ekv
the battery replacement is pretty straightforward on this type.
First remove the emergency key from the card, once this is out you can remove the battery. Below is a diagram to assist you.
Attachments are only available to registered users.
If the card needs programming then this has to be done using a suitable diagnostic tool.
I hope this helps.
