I have Z-Wave door locks and there’s no built-in way to manage them, set PIN Codes, schedules, etc.
Keymaster in HACS helps a lot, but something this basic to home automation should not be so complicated in Home Assistant.
In a lot of cases it depends on what the locks expose via their api.
My zigbee locks have to be configured entirely via the keypad. 
I use kwikset devices, so it may be different for yours, but i usually set the pins with the service call:
service: zwave_js.set_lock_usercode
data:
code_slot: 1
usercode: 1234
target:
entity_id: lock.carport_lock
