The smart unlock feature is intended to prevent you from unintentionally locking your IA key inside your vehicle’s passenger compartment.

When you lock your vehicle using the driver or passenger power door lock control (with the door open), after you close the door the vehicle will search for an IA key in the passenger compartment. If an IA key is found inside the vehicle, all of the doors will immediately unlock and the horn will chirp, indicating that the IA key is inside.

In order to override the smart unlock feature and intentionally lock the IA key inside the vehicle, you can lock your vehicle using your keyless entry keypad or using the control on another IA key. Refer to Keyless entry system in this chapter for more information on keyless entry keypad operation.
