- Debris in the Lock: Dirt, gunk, or small pebbles can lodge inside a lock or ignition cylinder. When the key is inserted and turned, the obstruction acts as a wedge, putting immense pressure on the key blade.
- Key Fob Shell Degradation: Most modern secrets are framed in plastic. Direct exposure to UV rays, skin oils, and unexpected drops can cause the plastic to crack, ultimately causing the internal circuit board falling out or the blade ending up being removed from the head.
Typical Causes of Electronic Failure
- Battery Depletion: The most typical "non-start" concern is simply a dead CR2032 or similar coin-cell battery.
- Circuit Board Damage: Dropping a key can desolder components or break the fragile PCB (Printed Circuit Board) inside the fob.
