Should still be under warranty so dealer’s problem.


If it is indeed a failing battery in the fob, as @weekend-warrior 's vid suggests, I strongly doubt it’s a warranty issue. Even if it were, we’re talking about a $2.99 battery and 5 minutes of labor. Why wouldn’t the OP just do it him/herself? If a new battery doesn’t solve the problem, then it becomes a warranty issue.
