How do you disarm a 1997 Lexus 400?

To disarm a 1997 Lexus 400, use the key fob to unlock the doors or insert the key into the driver's side door and turn it to unlock. If the vehicle is equipped with a factory alarm system, it typically disarms automatically when the doors are unlocked. If the alarm is still active, turning the ignition key to the "On" position may also help reset the system. If you encounter difficulties, consult the owner's manual for specific instructions related to the alarm system.
