Hai I have a 2012 Chevy Cruze LTZ and two weeks ago it displays code 91 while trying for push start. The key fob battery was replaced with a brand new one. The remote door lock is working. Keyless entry is also not working. Used the spare key also. Same result. Pl. Suggest a solution. Thanks
Thank you for writing in. There is an issue between the key and the car's computer system, and it pertains to the connection they need to share. Start by reprogramming the key with new batteries. Your owner's manual may give you more information if you want to try yourself. Otherwise a dealership would be your best bet to help you resolve the communication error.
