- Battery Exhaustion: The internal battery (generally a CR2032 or CR2016 cell) eventually passes away, cutting power to the transponder and remote transmitter.
- Environmental Damage: Exposure to moisture, extreme heat, or being dropped on hard surfaces can permanently damage the delicate electronic devices within.
