Why Won’t My BMW 2 Series Door Locks Respond to the Key Fob?

My BMW 2 Series key fob is not locking o r unlocking the doors. Could this be due to a weak key fob battery, faulty central locking system, o r a blown fuse? How can I troubleshoot and fix this issue in Pakistan?

Possible Causes:
🔹 Weak o r dead key fob battery – If the battery in your key fob is low, it won’t send a strong signal to the car.
🔹 Faulty key fob – A damaged fob o r worn-out buttons may stop working.
🔹 Blown fuse – A fuse related to the central locking system might have blown.
🔹 Weak car battery – If the car battery is weak, it may not provide enough power to the central locking system.
🔹 Faulty central locking module – The control module that manages the locks could be malfunctioning.

How to Fix:
✅ Replace the key fob battery – Try a fresh battery first.
✅ Check for signal interference – Other electronic devices nearby can block signals.
✅ Use the spare key fob – If the spare works, the primary key fob is faulty.
✅ Inspect the car battery – If its weak, recharge o r replace it.
✅ Check and replace fuses if necessary – Look at the fuse box for any blown fuses.
✅ Scan for errors with an OBD-II scanner – This can detect central locking faults.
