- Weather condition Extremes: Intense cold can make the metal of a key fragile. If a lock cylinder is frozen, using force to the key often results in a clean break.
- Debris in the Lock: Dirt, grime, 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 tremendous pressure on the key blade.
- Key Fob Shell Degradation: Most modern-day keys are enclosed in plastic. Exposure to UV rays, skin oils, and unexpected drops can cause the plastic to crack, eventually causing the internal circuit board falling out or the blade ending up being detached from the head.
Common Causes of Electronic Failure
- Battery Depletion: The most typical "non-start" problem is just a dead CR2032 or similar coin-cell battery.
- Circuit Board Damage: Dropping a key can desolder elements or crack the delicate PCB (Printed Circuit Board) inside the fob.
- De-programming: Occasionally, due to a serious voltage drop or electromagnetic interference, the transponder chip and the car's Engine Control Unit (ECU) may lose synchronization.
