I think one out of my two Roadster key fobs is broken. Had the SC replace both batteries during a service earlier today. One key fob works just fine. However, on the other, the Tesla "T" lock button does nothing. On that same fob, the middle unlock and lower trunk release button are actually working. So it looks like I have a broken "T" button on the one fob. Does anyone know of possible fixes to this? Do I need a whole new keyfob? Do they even make Roadster key fobs anymore? Can this be repaired? Can I at least salvage the key so a new one does not need to be cut?
