Can I turn off or change the locking function for my F51?

There is no way to change the lock function of the F51. The unit is equipped with a safety feature known as an egress, because of this safety feature the unit will always unlock when the internal handle is used If the door is locked. We do have an alternative option if the "panic proof feature" is not something you're fond of; the J54 from our Dexter line does not unlock when the internal handle is used.
