I received a message on the dash that the key battery needs replacing. I unwrapped a new battery using a tissue and cleaned top, bottom and edges of the battery before inserting it. I was holding it in a tissue at all times. The message was still shown. I then went out and bought another new battery, treated it the same way and obtained the same result. I tried resetting the system with the two scroll wheels and then the two scroll wheels and the brake. I still have the message, the spare key also produces the same message.
Is there anything else that I can try or is it a Tesla Service job?
