2. Physical Damage to the Housing
Key fobs are frequently dropped on concrete or stepped on. While the internal electronics may remain intact, a broken shell can enable moisture and dust to get in, or it might avoid the buttons from making correct contact with the internal switches.
3. Misaligned or Broken Buttons
