Vehicle cabin security apparatus, systems, and methods

A kit-of-parts for a door handle assembly of a passenger vehicle, comprising:

• at least one container;
• a door handle assembly that fits within the at least one container, the door handle assembly comprising:
• a door lock configured to adjust a door of a passenger vehicle between a locked position to impede access to a cabin through the door and an unlocked position to allow access to the cabin through the door, the door lock comprising a lock assembly and a lock stem, and
• a panel assembly configured to mount to the door, the panel assembly comprising a front panel portion and a back panel coupled to the front panel portion, the back panel comprising an aperture sized and configured to receive at least the lock assembly of the door lock into a slotted portion of the back panel;
• and
• a sleeve sized to fit over at the lock stem and configured to rotate about the lock stem in response to an external force or an external torque applied to the sleeve, the sleeve comprising a substantially constant inner opening dimension from a first end of the sleeve to a second end of the sleeve and configured to decouple the external torque applied to the sleeve from the lock stem to limit the external torque from being applied to the panel assembly through the lock stem sufficient to break the panel assembly by rotation of the lock stem exposed from a door handle in response to the external torque, the lock stem rotatable within the sleeve in response to rotation of a key in the door lock to adjust a door of the passenger vehicle between a locked position and an unlocked position.
