Diagnose the Problem

Carefully inspect the exterior door handle, the lock and the area around them for visible damage and try to operate the lock with the key and the handle to see if there is any response. 

Listen for any unusual sounds that might indicate a broken or disconnected part inside.

Gather Necessary Tools

You will likely need a flathead and Phillips screwdriver, needle nose pliers, a can of lubricant like WD-40 and potentially replacement parts specific to your vehicle model such as a new door handle, lock cylinder or linkage rod.

Access the Door Panel

Locate and remove screws that holding the interior door panel in place as these are often hidden under caps in the door handle or along the bottom edge. 

Use a panel removal tool or a flathead screwdriver to carefully remove the panel starting at the bottom and working around the edges. 

Be careful with any wiring harnesses connected to the door such as those for power windows or locks.

Inspect the Mechanism

Observe the linkage connecting the exterior handle to the lock and latch and look for signs of disconnection, breakage or bending and make sure that the door lock actuator if present is functioning correctly.

Lubricate Moving Parts

Apply a lubricant like WD-40 to all moving parts within the door including the hinges, latch and any linkages. This can help free up components that may have become stuck because of rust or debris.

Repair or Replace Faulty Parts

If any parts are damaged such as the exterior handle, lock cylinder or linkage rods replace them with new ones but make sure your replacement parts are the correct fit for your specific make and model.

Test the Door

Before fully reassembling the door test the external handle and lock and make sure they are working correctly. This may involve temporarily reconnecting any electrical components you disconnected.

Reassemble the Door Panel

Carefully position the door panel back into place making sure all clips and fasteners are aligned and only then reconnect any electrical connections and then the panel back into its original position.
Secure it with the screws you initially removed.

Seek Professional Help if Needed
