Onity HT22 - A Guest Wants to Change the PIN Code of an Htcombo Safe

Using the HT22 System - 40
A guest wants to change the PIN code of
an HTCombo Safe.
In order to change the PIN Code of an HTCombo safe,
a NEW GUEST key must be issued to the guest. In this
case, ALL the valid guest keys for that room MUST be
re-encoded, otherwise they will stop working in the
door.
This operation is not valid with the HT22P Encoder.
