My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting 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.
From what you have described here this sounds like a security component is disabling the starting of the vehicle.This can be due to an issue with the key itself needing replaced or an issue with one of the sensors reading the key causing this.What needs to be done from here is to have the fault codes checked/read out with a scan tool that will plug in and communicate with all computers to see what codes are set.Once this has been done the codes can be diagnosed to locate and repair the cause here.
Thanks Pete
