Direct exposure to UV rays, skin oils, and accidental drops can trigger the plastic to crack, eventually resulting in the internal circuit board falling out or the blade ending up being separated from the head.Common Causes of Electronic FailureBattery 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 split the fragile PCB (Printed Circuit Board) inside the fob.De-programming: Occasionally, due to a severe voltage drop or electro-magnetic disturbance, the transponder chip and the car's Engine Control Unit (ECU) may lose synchronization.2.
