1. A method of deactivating a secondary lock feature of a vehicle, the method comprising:
sensing a movement of an interior door handle of the vehicle with a sensing device;
determining a status of the secondary lock feature with a secondary lock switch to ascertain if the secondary lock feature is disposed in an active state in which the interior door handle does not open a door;
starting a timer to measure an elapsed time period since the sensing of the movement of the interior door handle;
sensing an environmental condition of an interior passenger compartment defined by the vehicle with a sensor;
setting an unlock delay time based on the environmental condition; and
when the secondary lock feature is disposed in the active state and the elapsed time period is greater than or equal to the unlock delay time, automatically generating a control signal to thereby deactivate the secondary lock feature.
