My Buying Guides on Toyota Highlander Key Fob Battery Replacement
Why I Replaced My Toyota Highlander Key Fob Battery

Then I snapped the fob back together and tested it right away. Once I saw the lock and unlock buttons working normally again, I knew the replacement was successful.
What I Checked Before and After Buying
