YES. exactly. who cares if your passenger door locks if you cannot lock the driver door? but the altman latches state that exactly- you cant lock doors from the inside.
so,..... unless someone has some new updates, it seems you are forced to install a lock cylinder on your "other" door or go without security. or stick with the original door latch systems, which seem to get worse all the time.
bummer. i'll keep digging.
