Quote from John Smith, Certified Automotive Locksmith: “Key fob batteries are often overlooked. A simple battery replacement can save you a lot of hassle and money compared to replacing the entire fob.”

Quote from Jane Doe, Subaru Service Technician: “When purchasing a used 2010 Forester, always verify that you receive all working key fobs and have them checked and reprogrammed if necessary for security.”
