- Particles in the Lock: Dirt, grime, or little pebbles can lodge inside a lock or ignition cylinder. When the key is placed and turned, the blockage functions as a wedge, putting tremendous pressure on the key blade.
- Key Fob Shell Degradation: Most modern keys are framed in plastic. Direct exposure to UV rays, skin oils, and accidental drops can trigger the plastic to break, eventually leading to the internal circuit board falling out or the blade ending up being detached from the head.
Typical Causes of Electronic Failure
- Battery Depletion: The most typical "non-start" problem is simply a dead CR2032 or similar coin-cell battery.
- Circuit Board Damage: Dropping a key can desolder components or break the delicate PCB (Printed Circuit Board) inside the fob.
