If Passive Locking is enabled, the doors should lock several seconds after you turn off the vehicle, exit with the key fob, and close all doors and the rear closure. But there are a few scenarios when this won’t work, including:
- If Passive Locking is not enabled. Make sure you’ve enabled this feature in the Settings menu by selecting: Settings > Vehicle > Remote Lock, Unlock, Start
- If all doors and the trunk/liftgate haven’t been closed, it won’t automatically lock
- If at least one key fob wasn’t removed from the vehicle, it won’t automatically lock
- If you haven’t turned the vehicle off, it won’t automatically lock
