My car was delivered 6 days ago. Last night the car did not recognize the FOB. I was able to open the car door with my iPhone app. Once in the car it said key not present and refused to turn on. Despite 30 minutes on the phone with Tesla, no luck. Had to catch a cab home, get the other FOB and then return to the car, where fortunately the second FOB worked and home I went. Today the Tesla rangers came by and found the FOB had somehow become "deprogrammed".
This episode raises a larger safety issue. All other car manufacturers that use an electronic FOB have a backup mechanical key to both get into the car and to start it. Not so with our Teslas!
They need to have a pincode or similar on the main touchscreen to allow one to start the car in case the FOB fails. Even with the reported upcoming software update allowing Tesla to start the car for you, this will only work if there is a 3G signal. If in the mountains or in a parking garage you will be out of luck..
Of all the proposed software updates this is the most important. The roadside assistant on the phone last night suggested carrying both FOBs for now as a safety! We should not have to do this with such a high tech car. I am hopeful that if others have had this issue and are concerned about inability to start the car in case of FOB failure, they will relay their urgent concern to Tesla for a fix.
