Canceling Anti-Theft System Setting
WARNING: This page is about a different car, the 2003 Lexus ES 300 and 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
When you unlock any door or trunk using an ignition key or wireless remote control, the system is cancelled. If you unlock any door or trunk with the wireless remote control, the turn signal lights flash twice.
