About the Security System
If Model 3 does not detect an authenticated phone, key fob, or key card and a locked door or trunk is opened, an alarm sounds. The headlights and turn signals also flash. To deactivate the alarm, press any button on the mobile app or tap your key card or key fob against the card reader located just below the Autopilot camera on the driver’s side door pillar.
To manually enable or disable the alarm system, touch . When enabled, Model 3 activates its alarm one minute after you exit, the doors lock, and a recognized key is no longer detected.
A battery-backed siren (if equipped) sounds in situations where a locked door or trunk is opened and Model 3 does not detect a key nearby. If you also want this siren to sound in situations where the vehicle detects motion inside the cabin, enable Tilt/Intrusion (see Tilt/Intrusion (if equipped)).
Tilt/Intrusion (if equipped)
The Security Alarm must be on to enable Tilt/Intrusion.
Tilt/Intrusion sounds the alarm in your vehicle if Model 3 detects motion inside the cabin, or is moved or tilted (for example, with a tow truck or jack). To enable, touch .
The intrusion sensor automatically disables in situations where the climate control system is operating when you leave your vehicle. To override, you can manually turn the Tilt/Intrusion Sensor on again after choosing Keep Climate On, Dog, or Camp Mode.
