Key Stopped Working 2012 A5
My second key stopped working. The battery is new and over 3V. Is there a sync procedure that needs to be done? As an aside, how can they cost $450?!

Yes..if the fob was left unpowered for too long.
Normally something like press the lock or unlock button and then unlock the car with the key. You could also google the key fob synch procedure.
YMMV.
