While sitting inside Model Y, you can lock and unlock all doors and trunks by touching the lock icon on the touchscreen.
The icon changes to indicate whether doors are locked or unlocked.
You can also unlock the doors by pressing the Park button on the end of the drive stalk a second time. Pressing this button once engages Park and pressing it again unlocks the doors.
Driver Door Unlock Mode
Enabling Controls > Locks > Driver Door Unlock Mode only unlocks the driver door when you first unlock Model Y.
Walk-Away Door Lock
Doors and trunks can automatically lock when you walk away carrying your phone key or paired key fob. To turn this feature on or off, touch Controls > Locks > Walk-Away Door Lock.
When the doors lock, the exterior lights flash once and the mirrors fold (if Fold Mirrors is on). To also hear a confirmation sound when Model Y locks, touch Controls > Locks > Lock Confirmation Sound.
Model Y does not automatically lock if:
NOTE: If Model Y detects an authenticated key for five minutes after you exit the vehicle and close all doors, Walk-Away Lock disables and doors do not lock when you walk away. In this case, you must manually lock your vehicle until after your next drive.
NOTE: It is ultimately your responsibility to ensure your vehicle is locked, even when Walk-Away Door Lock is enabled.
Drive Away Locking
Model Y automatically locks all doors (including the trunks) when your driving speed exceeds 5 mph (8 km/h).
Child Locks
Model Y has child locks on the rear doors to prevent them from being opened using the interior release buttons. On the touchscreen, touch Controls > Locks > Child Lock. You can choose Both to engage the child lock on both rear doors, or you can choose Left or Right to engage it on just a specific door.
WARNING: It is recommended that you turn on child locks when children are seated in the rear seats.
Unlock on Park
When you stop Model Y and engage Park, you can choose to unlock all doors. To turn this feature on or off touch Controls > Locks > Unlock on Park.
NOTE: If set to OFF, you can unlock all doors by pressing the Park button a second time after engaging Park.
