This procedure covers the replacement of a rear door lock actuator on a 2012-2017 Toyota Camry with a 2.5L I4 engine, including door panel removal, actuator replacement, and verification of proper lock operation.

Warnings

Tools required

Parts

• Rear door lock actuator × 1 — Use OEM specification or quality aftermarket
• Door panel clips (if damaged) × 1 — Toyota OEM door panel clips

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal and wait 90 seconds
3. Roll down rear window completely to prevent damage during door panel removal
4. Gather all tools and replacement actuator

Procedure

1. 1

   Remove door panel screws
   Remove the Phillips screw from inside the door pull handle pocket. Remove the screw behind the interior door handle trim cover (pry cover gently with flat-head screwdriver). Locate and remove the screw at the bottom rear corner of the door panel.
   Torque spec

   Cover Screws11 Nm (8 lb-ft)
2. 2

   Disconnect door handle cable
   Carefully pry the interior door handle trim bezel away from the door panel. Reach behind and disconnect the door handle cable by sliding the cable end out of the handle lever, then unhooking the cable housing from its retaining clip.
3. 3

   Remove door panel
   Starting at the bottom rear corner, use a panel removal tool to carefully release the retaining clips around the perimeter of the door panel. Work your way around the panel, releasing each clip. Once all clips are released, lift the panel upward to disengage it from the window sill, then pull away from door.
4. 4

   Remove vapor barrier access
   Peel back the plastic vapor barrier sheet carefully at the area behind the door latch assembly. You only need to expose enough area to access the lock actuator mounting bolts and electrical connector. Do not remove the entire vapor barrier.
5. 5

   Disconnect actuator electrical connector
   Locate the lock actuator electrical connector (typically a blue or gray connector). Press the locking tab and disconnect the connector from the actuator. Note the routing of the wire harness for reinstallation.
6. 6

   Disconnect actuator rod linkages
   Identify the two plastic rod linkages connected to the actuator: one from the door lock knob and one to the latch mechanism. Use a flat-head screwdriver to carefully pry each rod end off its ball socket on the actuator. Note the position of each rod for proper reconnection.
7. 7

   Remove actuator mounting bolts
   Remove the three 10mm mounting bolts securing the lock actuator to the door frame. Support the actuator as you remove the final bolt. Carefully maneuver the actuator out through the access hole in the door frame.
   Torque spec

   Module Mounting Bolts8 Nm (6 lb-ft)
8. 8

   Install new actuator
   Position the new lock actuator into the door frame, aligning the mounting holes. Install the three mounting bolts finger-tight first, then torque to specification. Ensure the actuator is properly seated against the door frame before final torquing.

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Reconnect rod linkages and electrical connector
   Snap the plastic rod linkages back onto their respective ball sockets on the new actuator. Verify each rod is fully seated by gently pulling on it. Reconnect the electrical connector to the actuator until it clicks into place.
10. 10

    Test actuator operation
    Before reinstalling the door panel, reconnect the negative battery terminal temporarily. Use the door lock switch and key fob to test the new actuator operation. Verify the lock engages and disengages smoothly and the lock knob moves correctly. Disconnect battery again before proceeding.
11. 11

    Reinstall vapor barrier and door panel
    Press the vapor barrier back into place, ensuring it adheres properly to the door frame. Reconnect the interior door handle cable to the handle lever and secure the housing in its clip. Position the door panel onto the door, engaging the top edge into the window sill first, then press firmly around the perimeter to seat all clips.
    Torque spec

    Cover Screws11 Nm (8 lb-ft)
12. 12

    Reinstall battery and final verification
    Reconnect the negative battery terminal and torque to specification. Test all door lock functions: interior switch, key fob remote, and manual lock knob. Verify the child safety lock still functions if applicable. Test door opening from inside and outside.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all door panel clips are properly seated before applying pressure
2. Verify door handle cable is properly routed and connected before securing panel
3. Check that all screws are reinstalled in their original locations

Verification

• Test door lock operation with interior switch in both lock and unlock positions
• Test door lock operation with key fob remote from outside vehicle
• Manually operate the lock knob to verify smooth movement
• Open door from inside and outside to ensure latch operates correctly
• Listen for any abnormal noises during lock actuation
• Verify child safety lock operates correctly if applicable
