For immediate locking, switch the ignition off, remove the fob, close every door, and press any exterior door-handle button.
- 04
For delayed automatic locking, open Settings > Vehicle > Remote Lock, Unlock and Start and turn on Passive Locking; then leave with the fob and close all doors.
Important limits
- The fob must be outside the vehicle and all doors must be closed before passive locking can complete.
- Unlock behavior can differ if the Remote Lock, Unlock and Start preferences have been customized.
Quick checks.
