UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have 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.In order to try and determine why the immobilizer system is active and not reading your keys you are going to need to start with scanning the system to see what the fault code and or codes are that should be setting . If you can get this done and post back with the results we can work from there to try and determine the cause.
Unfortunately about the only other thing you can do is try using your spare key. If it still will not start then its going to require some hands on testing starting with a scan.
