Why do the power door locks on my Hyundai Sonata lock and unlock randomly without pressing any button?

Sometimes the power door locks operate by themselves—locking and unlocking randomly without any input. What could cause this erratic behavior?

Random locking/unlocking is usually caused by:

A faulty key fob sending false signals due to a stuck button o r internal damage.

Issues with the central locking module, including software glitches o r short circuits.

Electrical problems like water ingress o r damaged wiring causing unintended commands.

Recommendation:

Replace o r repair the key fob battery o r unit.

Have the central locking module inspected by a qualified technician.

Check for moisture o r wiring damage inside door panels.
