Dropping a key on a tough surface or exposing it to water can harm the internal PCB (Printed Circuit Board). This can lead to intermittent button response or a total loss of communication with the automobile.
3. Physical Wear of the Blade
For keys that need insertion into a cylinder, the grooves on the blade can wear down in time. Ultimately, the key will no longer align with the internal wafers of the ignition or door lock.
4. Snapped or Broken Blades
