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.
Try and disconnect the battery for about 5 minutes then reconnect it with the key off and see if this resets the electronics to where it can be reprogrammed again and to see if everything else starts to operate again.If this does not work I would have the fault codes checked/read out of all computers to see what codes are set.This will require using a scan tool/computer that will plug in and communicate with all computers in your vehicle here.Any codes set will need diagnosed to locate and repair the fault here.It is possible one or more control modules may have an internal fault due to the programming fault and need replaced.
