When a residential rental unit is permanently vacated by all tenants, the landlord shall re-key or replace all door locks that are exclusive to that unit, including all entrance door locks on the vacated unit and any locks on separate entrance doors to any storage and/or garage facility exclusively used in connection with the use or occupancy of the vacating tenants. All of the following conditions apply:
(a) If two or more locks on any one door are subject to the re-key and replacement provisions of Section 49B.2 and open by different keys, the landlord must re-key or replace only one of the locks on the door.
(b) If the same key opens two or more locks subject to the re-key and replacement provisions of Section 49B.2, the landlord must re-key or replace all locks opened by that key.
(c) The re-key and lock replacement requirements of this Chapter do not apply to any door locks that are provided for use by two or more units.
