- Battery Exhaustion: The internal battery (typically a CR2032 or CR2016 cell) ultimately dies, cutting power to the transponder and remote transmitter.
- Environmental Damage: Exposure to wetness, extreme heat, or being dropped on hard surfaces can completely harm the delicate electronic devices within.
