2. Physical Damage to the Housing
Key fobs are often dropped on concrete or stepped on. While the internal electronics might remain undamaged, a broken shell can allow moisture and dust to get in, or it may prevent the buttons from making correct contact with the internal switches.
3. Misaligned or Broken Buttons

4. Circuit Board Corrosion
If a key fob is immersed in water or exposed to high humidity, the internal copper traces can wear away. This interrupts the flow of electricity and triggers periodic or overall failure.
5. Signal Desynchronization
In some circumstances, the rolling code between the lorry's receiver and the key fob can fall out of sync. This typically occurs after a battery modification or if the buttons are pressed consistently while out of variety of the lorry.
