Locks Anti-Theft Alarm System After the vehicle is locked (including the front hood and tailgate) from the outside with the smart key fob, the NIO app, the NFC feature, or the emergency key, the anti-theft alarm system is activated automatically. When someone tries to open the door without carrying an authenticated smart key fob (or carrying one without a valid authorization), the anti-theft alarm will be triggered. At this time, the turn signals will flash and the horn will honk. You can unlock the vehicle from the outside with the smart key fob, the NIO app, or the NFC key to deactivate the anti-theft alarm.
Caution If the key fob’s battery is low and you need to unlock the vehicle with the emergency key, please place the key fob level on the front cup holder next to the center console within 15 seconds and ensure the button on the side of the key fob is facing the rear of the vehicle. Next, sit in the driver’s seat and close the driver’s side door or press the brake pedal. Otherwise, the anti-theft alarm will be activated. 22
