Locking/Unlocking Operation: Locking
WARNING: This page is about a different car, the 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
When you push the LOCK button on the key briefly, all the doors can be locked from the outside of the vehicle. At this time, 1 beep sounds and the turn signal lights flash once (the turn signal lights can be set not to flash and the volume of beep sound can be changed). However, when you push the LOCK button with any door not closed securely, the buzzer sounds for 10 seconds (the buzzer can be set not to sound with any door not closed securely). To stop the buzzer, close all the doors securely or push the UNLOCK button. If the key is in the ignition switch, locking cannot be done. Do not push the LOCK button any longer than 2-3 seconds. Pushing the button longer activates the alarm.
