Door Lock Actuator - Front

This procedure covers the removal and replacement of a front door lock actuator on a 2018-2024 Honda Accord with the 1.5L turbo engine.

Warnings

Tools required

Parts

• Front door lock actuator × 1 — Honda 72115-TVA-A01 (driver) or 72155-TVA-A01 (passenger)
• Door panel trim clips × 5 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key fob from vehicle interior
3. Open the hood and disconnect the negative battery terminal to prevent accidental power window or lock activation
4. Allow at least 3 minutes after battery disconnect for airbag system capacitors to discharge
5. Gather all replacement parts and verify correct actuator for driver or passenger side

Procedure

1. 1

   Remove door panel screw covers
   Locate and carefully pry off the small screw cover caps on the door panel. There is one in the door pull/armrest area and one near the interior door handle. Use a trim removal tool or small flathead screwdriver wrapped in tape to avoid scratching the trim.
2. 2

   Remove door panel mounting screws
   Remove the Phillips screws behind the cover caps you just removed. There are typically two screws in the armrest area and one near the door handle trim. Keep these screws organized as they may be different lengths.
3. 3

   Disconnect door handle trim
   Carefully pull the interior door handle trim piece away from the door panel. It is held by clips. Disconnect the small electrical connector for the door handle accent lighting if equipped. Set the trim piece aside safely.
4. 4

   Release door panel clips
   Starting at the bottom rear corner of the door panel, use a trim removal tool to carefully release the retaining clips around the perimeter of the panel. Work your way around the panel, pulling gently outward and upward. There are approximately 8-10 clips holding the panel. Listen and feel for each clip releasing.
   ⚠Do not pull the panel completely away yet as electrical connections are still attached behind it.
5. 5

   Disconnect electrical connectors
   With the door panel pulled away from the door frame, reach behind and disconnect all electrical connectors. This includes the power window switch, power lock switch, power mirror switch (driver side), and any puddle lamp or speaker connectors. Press the locking tabs while pulling connectors straight out. Completely remove the door panel and set it aside on a clean, protected surface.
6. 6

   Remove door moisture barrier
   Carefully peel back the plastic moisture barrier sheet enough to access the door lock actuator area near the door latch assembly. The barrier is held by adhesive. You only need to peel back the section near the latch mechanism, not remove it entirely. Be careful not to tear the barrier.
7. 7

   Locate and access the door lock actuator
   Using a flashlight, locate the door lock actuator assembly. It is integrated into or mounted adjacent to the door latch mechanism on the rear edge of the door. You will see the actuator motor housing and the connecting rod linkage that operates the lock mechanism.
8. 8

   Disconnect actuator electrical connector
   Disconnect the electrical connector from the door lock actuator by pressing the locking tab and pulling the connector straight off. Note the routing of the wire harness for reinstallation.
9. 9

   Disconnect actuator linkage rod
   Disconnect the plastic linkage rod that connects the actuator to the door latch mechanism. This typically requires releasing a plastic clip by pressing or sliding it, then pulling the rod free from the ball socket. Note the exact position and orientation for reassembly.
   ⚠Linkage clips can be fragile. Work carefully to avoid breaking the clip or rod connection point.
10. 10

    Remove actuator mounting fasteners
    Remove the mounting screws or bolts holding the actuator to the door or latch assembly. These are typically T20 Torx or 10mm bolts. There are usually 2-3 fasteners. Keep track of any spacers or washers.
11. 11

    Remove old actuator
    Carefully maneuver the old actuator out through the access opening in the door structure. You may need to rotate or angle it to clear the door frame. Take note of its orientation for installing the new actuator.
12. 12

    Install new actuator
    Position the new actuator in the same orientation as the old one and guide it into place through the door frame opening. Align the mounting holes with the door or latch assembly. Install the mounting fasteners and tighten to 8.0 Nm (6 lb-ft) using a torque wrench.

    Module Mounting Bolts8 Nm (6 lb-ft)
13. 13

    Reconnect linkage and electrical
    Reconnect the linkage rod to the actuator and door latch mechanism, ensuring the plastic clip fully seats. Reconnect the electrical connector to the actuator until it clicks into place. Gently tug to verify it is secure.
14. 14

    Test actuator function
    Temporarily reconnect the battery negative terminal and test the door lock actuator function using the key fob and interior lock switch. Verify the lock and unlock functions work smoothly in both directions. If satisfactory, disconnect the battery again for door panel reinstallation.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
15. 15

    Reinstall moisture barrier and door panel
    Press the moisture barrier back into place, ensuring good adhesive contact. Reconnect all electrical connectors behind the door panel (window, lock, mirror switches, etc.). Align the door panel with the door frame and press firmly around the perimeter to seat all clips. Reinstall the door panel mounting screws. Reinstall the interior door handle trim and screw covers.

Reassembly

1. Ensure all door panel clips are fully seated before reinstalling screws
2. Verify the moisture barrier is properly sealed to prevent water intrusion
3. Double-check that all electrical connectors are fully engaged
4. Replace any broken trim clips with new ones

Verification

• Reconnect the battery negative terminal and torque to 6.0 Nm (4 lb-ft)
• Test door lock operation from all sources: key fob, driver door switch, passenger door switch, and interior lock button
• Verify smooth lock and unlock operation without binding or unusual noise
• Test that the lock status indicator on the dash responds correctly
• Initialize power windows by fully lowering then raising each window and holding the switch up for 2 seconds after full close
• Check that the door panel is secure with no rattles or loose clips
• Set radio presets and clock as needed
