A non-egress window for motor vehicles selectively removable for servicing, in which an exterior frame having a connector mounts in an opening in a sidewall of a motor vehicle and a window frame with a window pane attaches to the connector. A pair of latch keepers mount in spaced-apart relation to the exterior frame opposing the connector. A release bar in the exterior frame opposing the connector selectively moves between a first position and a second position relative to the latch keepers by a tool selectively brought into contact with the release bar. A pair of latch catchers attached to the release bar engages the latch keepers with the release bar in the first position and disengage from the latch keepers with the release bar in a second position. A method of removing a non-egress window from a motor vehicle is disclosed.
