Over time, this mechanical stress causes:

1. Cracked Solder Joints: The internal parts are soldered to the circuit board. Bending the card triggers these tiny solder indicate fracture, breaking the electrical connection.
2. Loose Microswitches: The physical buttons inside the card can remove from the board.
3. Battery Exhaustion: The internal battery (generally a CR2032 or CR2016 cell) ultimately passes away, cutting power to the transponder and remote transmitter.

  • Use a fine-tip soldering iron to reflow the solder.
  • Glue the plastic case back together using a strong plastic adhesive.

Warning: DIY casing repair carries a high danger of permanently ruining the internal circuit board if done incorrectly.
