I see there any pictures or videos on how to replace the driver door handle and lock ?

IF THE LOCKS ARE NOT ON THEN THE HANDLE NEEDS TO BE REPLACED

Make sure if it is equipped with a child safety lock on the inside of door jamb below or above the latch is unlocked. If that is ok then check to be sure the cable or rod to the interior handle is properly connected to the latch, remove door panel and if you can't see it directly you may have to use a mirror and flashlight to see if all is connected if so work the interior door handle while looking at all moving parts and tracking down where it is not doing it's function.

Handle is more than likely broke and needs replacing. Rod no longer on handle. Suggest Taking of off door panel to inspect.

On a S60, 2012, (drivers door) you first remove the plastic cover in under which you find the lock (with keyhole).
secondly, open the door and remove the 15 mm diameter plastic cover near the handle. Insert a long torx scrwdriver(T25 ?) in the
opening and while keeping the door handle "open" (this gives you the possibility to easily replace the handle later) Turn the torx until it stops
(do not use much force). Now you can pull out the metallic lock, peer
out the small white plastic under the door handle and pull out the handle. Do not turn the torx before you have replaced the handle.

In the case of back door, you start by finding the hole for the torx under the doors rubber sealing near the door handle.

If I recall correctly the door handle should be similar to the F150. The rod should have a plastic at the end that hooks to a mechanism where the inside door handle should go. I have a clip for you which you could use as reference.
In case the handle is different it may be the second type which connects directly to the handle. It should hook to the handle but you will have to turn the handle to get the rod locked. This video is from an explorer.

remove the screws that fasten the interior door panel to the door.  Visually inspect the handle assembly. there will be two cables that connect the handle and lock button to the door lock assembly.  I would bet that the L-shaped end of the interior door handle cable broke.  The replacement is self explanatory for the handle. Google the door lock assembly which isn't as visable.  Bob

Power Door Lock Operation (Front Doors)
The front doors do not have traditional door lock actuators. They have electronically controlled door latches that will operate depending on the status of the door lock system. This status is determined by the front door modules and the last known state of the lock system. If the last known state is LOCK, the latches will not release when the door handles are operated. If the last known state is UNLOCK, the latches will release when the door handles are operated. The front doors are also equipped with red door lock status indicators. The front door modules will supply power and ground to the indicators to illuminate them when the lock system is in a virtual state of lock. The indicators will not continuously illuminate when the vehicle is locked. They will illuminate for approximately 5 seconds after a lock switch activation or after a door handle has been operated and the front door modules are in a virtual state of lock. For further information on the front door latches, refer to Power Door Latch Description and Operation .
I would assume they check for DTC'S - diagnostic trouble codes ?
DTC B3062 Front Door Key Lock Switch Circuit
• DTC B3067 Front Door Key Unlock Switch Circuit
DTC B3849 Exterior Door Handle Switch Circuit
The left front exterior door handle and right front exterior door handle switch signal circuits provide inputs to the driver door module (DDM) and passenger door module (PDM) when an exterior door handle switch is activated. These inputs allow the door module to detect a door open request. The door modules provide voltage to the door handle switches. If the door module detects that a ground is applied for greater than 30 seconds continuously, a DTC is set and the door module will ignore the door handle switch input.

Cadillac CTS Door Handle Repair Micro Switches Replacement 2nd Gen

according to my partsman (who has had great advice for many years), you do not have to remove the door panel to replace the door handle which contains the cylinder lock. the handle is released with a screw which you can see when you open the door. you will need a starhead screwdriver or socket. A new handle costs around $40 at a parts store in my area. call around for a locksmith who will re-key your key to the new lock or use the key which comes with the new lock, your choice. i am in dealing with this also
