Physical Damage

The most obvious form of failure is physical damage. This can consist of a snapped metal blade, a cracked plastic case, or buttons that have actually worn down or fallen out. When the casing cracks, the internal circuit board ends up being susceptible to debris and wetness.

Electronic Malfunction

Electronic failure often takes place within the circuitry of a remote or smart key. Components like micro-switches can desolder from the circuit board due to effect or heat. Additionally, if a key is immersed in water, the fragile traces on the PCB (Printed Circuit Board) can corrode.

Battery Depletion

A common misunderstanding is that a key is "broken" when it merely requires a new power source. While mechanical functions may still work, the remote entry and proximity begin features will stop working as soon as the internal CR-style battery dies.
