2. Broken Key Blades
Mechanical failure frequently takes place where the metal blade fulfills the plastic real estate. In "flip" keys, the internal pin or spring mechanism can snap, leaving the blade dangling or detached.
3. Worn or Damaged Buttons
Over time, the rubber buttons on a fob can use down or tear, allowing dirt and moisture to penetrate the internal circuit board. In some cases, the tactile switch soldered to the circuit board itself might break off.
4. Transponder Desynchronization
Often, the car and the key "lose" their connection. This can happen if the car battery passes away or if the key is dropped. The car may open, but the engine will not start due to the fact that the immobilizer does not acknowledge the transponder chip's code.
