Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Carry the electronic key outside the vehicle and close every side door.
- 02
Leave the power liftgate open and start its automatic closing operation.
- 03
While the liftgate is closing, press Lock on the wireless remote or use the Smart Key lock control.
- 04
Keep clear while the liftgate completes its movement.
- 05
Wait for the buzzer and emergency-flasher confirmation that every door has closed and locked.
- 06
Physically verify the final lock before leaving the vehicle.
Important limits
- Keep the electronic key outside; placing it inside after the closing cycle begins can result in it being locked in the vehicle.
- If jam protection or another problem prevents full closure, reserve lock is canceled and all doors unlock.
- The confirmation signal must not replace checking that the liftgate fully latched and the vehicle locked.
Quick checks.
- ✓If the Highlander unlocks again, clear the obstruction, confirm the cargo does not contact the door and repeat the complete sequence.
- ✓If reserve lock does not arm, confirm every side door is closed before starting the automatic liftgate-closing operation.
- ✓If the power liftgate will not move automatically, confirm that its system is enabled.
