Note: The door lock consists of an inner and outer part. If the outer part is faulty, it can be replaced without removing the door trim. When replacing or repairing the inner part of the lock, the door trim must be removed.
Removal
1. Remove the door trim.
2. Remove the plastic film from the front door.
3. Using a Phillips screwdriver, unscrew the three screws securing the inner door opening handle.
4. Disconnect the inner handle rod from the lock:
a) Using an awl, remove the retainer from the lock lever pin.
b) Remove the washer and the rear end of the inner handle rod from the pin.
5. Remove the inner handle assembly with the rod.
6. Using a slotted screwdriver, disconnect the plastic ends of the outer lock handle rod (3) and the lock cylinder rod (2) from the lock levers. The end of the lock button rod (1) does not need to be disconnected.
7. Disconnect the central lock wire connectors.
8. Unscrew the two lock screws and remove the outer part of the lock.
9. Remove the inner part of the lock together with the locking button rod and the central lock switch from the door.
Note. The front right door has a lock blocking gear motor. It is removed in the same way as the rear door motor. On vehicles equipped with a remote-controlled alarm system, the front door may also have a lock blocking gear motor.
10. Before removing the lock retainer, mark its position on the middle pillar of the body (with a marker or felt-tip pen).

11. Remove the lock retainer.
Note: There may be shims installed under the retainer. These should be installed in place during assembly.
Installation
We install the door lock and all previously removed parts on the car in the reverse order.
Helpful Hint: It is convenient to use sliding pliers to put the plastic tips on the ball joints of the lock levers.
We install the lock retainer according to the marks applied to the body pillar. If the door does not close well (for example, with a metallic knock or having to slam the door hard to close it), adjust the lock.
Adjustment
Note: The door lock is adjusted by changing the position of the latch on the rack. When closing the door, the protruding part of the latch body should not touch the door and the elements of the outer part of the lock.
The pin of the lock must enter the slot of the outer part of the lock without touching the edges of the slot.
1. Loosen the locking pin and two locking screws (see item 9). By changing the position of the locking pin in the vertical plane, we achieve the optimal position of the locking pin in the slot of the lock.
2. We adjust the door closing density by moving the lock in the horizontal plane.
3. If the retainer touches the lock or the door, then we accordingly increase or decrease the number of adjusting linings installed under the retainer.
Helpful Hint: You can make your own additional adjustment shims by cutting them out of sheet metal (aluminum).
4. After completing the adjustment, tighten the mounting screws and the front door lock retainer pin.
