Gradually, this mechanical stress leads to:
- Cracked Solder Joints: The internal components are soldered to the circuit board. Bending the card triggers these tiny solder indicate fracture, breaking the electrical connection.
- Loose Microswitches: The physical buttons inside the card can detach from the board.
- Battery Exhaustion: The internal battery (typically a CR2032 or CR2016 cell) ultimately dies, cutting power to the transponder and remote transmitter.

- Use a fine-tip soldering iron to reflow the solder.
- Glue the plastic housing back together using a strong plastic adhesive.
Caution: DIY casing repair brings a high danger of permanently damaging the internal circuit board if done incorrectly.
