🔹 Wiring issues o r short circuit – Damaged wires in the door harness can trigger random locking/unlocking.
🔹 Key fob stuck in a loop – A faulty key fob may be sending repeated signals.
🔹 Malfunctioning central locking module – The module that controls the locks could be failing.
🔹 Moisture o r corrosion in wiring – Pakistan’s humid o r rainy weather can cause wiring problems.
How to Fix:
✅ Check if the key fob is stuck – Remove the battery from the key fob to see if the problem stops.
✅ Inspect door lock actuators – If one door is behaving abnormally, its actuator may need replacement.
✅ Check the wiring in the door harness – Look for frayed o r damaged wires.
