Random locking/unlocking can be caused by:

Faulty Wiring: Damaged wiring in the lock system can cause erratic behavior.
Malfunctioning Control Module: The central locking control module may have developed a fault.
External Key Fob Interference: Nearby signal interference can cause this behavior.

Fix:

Check the wiring for any shorts o r damaged areas.
Inspect the control module and reset o r replace it if necessary.
