- Battery Exhaustion: The internal battery (usually a CR2032 or CR2016 cell) ultimately dies, cutting power to the transponder and remote transmitter.
- Environmental Damage: Exposure to moisture, severe heat, or being dropped on tough surface areas can permanently harm the delicate electronics within.
