Difficulty: Intermediate · About 60 min · Toyota Highlander

Replace the rear hatch lock cylinder on a 2000–2007 Toyota Highlander, preserving the hatch handle linkages and restoring the interior trim without breaking its clips.

Steps

1. Remove the hatch trim panel

   Pry off the upper and side trim pieces and the pull-handle cover. Remove the handle bolt, release the panel clips, and lift the trim away carefully.

2. Remove the exterior hatch handle

   Release the lock-rod clip and remove the handle fasteners. Move the handle out enough to disconnect its control cable, then remove the garnish fasteners as needed.

3. Remove the lock cylinder

   Unclip the cylinder rod from the lock mechanism and withdraw the rod. Remove the cylinder mounting bolts and lift the old cylinder out of the hatch.

4. Install the replacement cylinder

   Place the new cylinder into the hatch opening and secure it with its bolts. Reconnect the lock rod and confirm the retaining clip is fully engaged.

5. Reinstall the handle and garnish

   Reconnect the control cable and position the exterior handle. Reinstall the handle and garnish fasteners, checking that the cable is routed without kinks.

6. Restore trim and test the lock

   Align the trim panel and press its clips into place. Reinstall the pull-handle bolt and trim covers, then test the key, latch, and release with the hatch open.

Check your vehicle’s repair manual for exact specifications and fit.
