- 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 clean break.
- Debris in the Lock: Dirt, grime, or small pebbles can lodge inside a lock or ignition cylinder. When the key is placed and turned, the obstruction functions as a wedge, putting tremendous pressure on the key blade.
- Key Fob Shell Degradation: Most modern secrets are encased in plastic. Direct exposure to UV rays, skin oils, and unintentional drops can trigger the plastic to split, ultimately causing the internal circuit board falling out or the blade becoming separated from the head.
Typical Causes of Electronic Failure
- Battery Depletion: The most common "non-start" problem is just a dead CR2032 or comparable coin-cell battery.
- Circuit Board Damage: Dropping a key can desolder parts or crack the delicate PCB (Printed Circuit Board) inside the fob.
- De-programming: Occasionally, due to an extreme voltage drop or electro-magnetic interference, the transponder chip and the car's Engine Control Unit (ECU) might lose synchronization.
