Steve Q Posted December 31, 2022 Share Posted December 31, 2022 Try reprogramming the key via this YouTube video: Also if you have a spare key you could try and use that, as it might help narrow down whether the issue is with the key or the car. If that doesn't work then I'd recommend a diagnostic check to see if any fault codes flag up Quote Link to comment Share on other sites More sharing options...
