- Weather Extremes: Intense cold can make the metal of a key fragile. If a lock cylinder is frozen, applying force to the key often leads to a tidy break.
- 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 functions as a wedge, putting tremendous pressure on the key blade.
- Key Fob Shell Degradation: Most contemporary secrets are enclosed in plastic. Direct exposure to UV rays, skin oils, and unexpected drops can cause the plastic to split, eventually leading to the internal circuit board falling out or the blade ending up being separated from the head.
Typical Causes of Electronic Failure
- Battery Depletion: The most common "non-start" issue is merely a dead CR2032 or similar coin-cell battery.
- Circuit Board Damage: Dropping a key can desolder elements or break the delicate PCB (Printed Circuit Board) inside the fob.
