My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

This issue here can be caused by a fault with the immobilizer itself not reading the key needing replaced as I have seen before in the past or the control unit/ecu itself for the immobilizer.If you have not had the fault codes read out/checked to see what codes are set this needs done.Any codes set need diagnosed to help locate and repair this issue here.If you have checked for codes and no codes were set let me know so we can continue or if you know the code post it here.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
