Electronic Malfunction
Electronic failure frequently occurs within the circuitry of a remote or smart key. Elements like micro-switches can desolder from the circuit board due to impact or heat. Additionally, if a key is immersed in water, the delicate traces on the PCB (Printed Circuit Board) can corrode.
Battery Depletion
A common mistaken belief is that a key is "broken" when it merely needs a new source of power. While mechanical functions may still work, the remote entry and distance start features will stop working when the internal CR-style battery passes away.
Signal De-synchronization
