Installation recommendations

Generally/Typically changing a set of locks involves work on both mechanical and electrical parts (switch box) and the exact steps may vary by car model. Consider the procedure below as a practical guide for this type of part.

1) Before assembly

• Check that the kit includes everything as described: switch box, driver’s door lock, tank cap/lock and 1x planchet.
• Compare the codes 4162CQ / 4162X4 with the original part (label/marking on the part or in the car documentation).
• Check the mechanical condition: smooth running of the inserts, unsqueezed grooves, no cracks or deformations.
• At the switch box, check the connectors and wiring – they must not be damaged or oxidized.

2) Necessary tools and materials

• Basic set of screwdrivers and bits (Torx/hex depending on design)
• Ratchet with attachments, possibly extension
• Pry tools for removing plastic coverings (trim tools)
• Pliers, small safety hooks/picks and clips
• Contact cleaner (for electrical connectors), clean cloth

3) Step-by-step assembly procedure

1. Disconnect the battery (minimize the risk of a short circuit when working on the switch box).
2. Secure the car against movement and prepare a place for storing screws and parts.
3. Dismantle the necessary plastic covers in the area of the switch box (the procedure varies depending on the design).
4. Disconnect the electrical connectors of the switch box – release the connectors carefully without pulling on the cables.
5. Unfasten the switch box and remove the original part.
6. Install the switch box from this kit and reconnect the connectors (check for proper seating and securing of fuses).
7. Dismantle the original insert/lock of the driver’s door (depending on the door design, it may be necessary to remove the interior trim and access the pulls).
8. Move the rods/controls to the new lock in the same arrangement and refit it.
9. Replace the tank cap/lock with a part from this kit (if included in the kit and replaceable separately on the car).
10. Before completely assembling the plastics, test the mechanics several times with the key: locking/unlocking the doors and operation of the ignition box.
11. Reinstall all covers, trims and fasteners.
12. Connect the battery.
• 4) Post-assembly checks and test drive/function verification
  • Verify the smooth turning of the key in the ignition box and the correct operation of the switching.
  • Check driver’s door locking/unlocking with key (no stuttering).
  • Verify function of tank lid/lock (if included and used for locking).
  • When driving for the first time, observe whether there are any electrical failures related to the switch box connector (typically a sign of a poorly seated connector).

  5) The most common assembly mistakes + how to avoid them

  • Not matching part codes – always verify 4162CQ / 4162X4 against original designation.
  • Damage to the switch box connectors – release the connector fuses in the correct direction, do not pry with force.
  • Poor positioning of the door handles – test the operation of the lock and handle before installing the upholstery.
  • Plastic composition without continuous control – do the function test before the final covering, save yourself repeated disassembly.

  Reasons why the part is damaged

  • Wear of the inserts and key – squeezed tumblers in the insert, impaired insertion and rotation of the key.
  • Pollution and corrosion – dust and moisture in the liners cause sticking and increased wear.
  • Forcible entry / attempted theft – damage to the door panel or switch box.
  • Mechanical stress – bent or worn key, prying with a frozen lock.
  • Electrical defects in the switch box – tired contacts or transition resistances in the connectors (manifested by irregular function).
