Igloo and ResortLock door locks are supported by the RemoteLock API and can be managed through OwnerRez -- simply treat them as being a RemoteLock using those instructions.
Since these are algorithmic instead of programmable locks, they do have some limitations when compared to other locks supported by RemoteLock:
Format: 10 digit codes are generated automatically by the lock based on stay dates
Setting Codes: Igloo and ResortLock does not support setting codes, only the auto generated code
Updating Dates: Igloo and ResortLock does not support modifying the dates for a given code. If you change the dates for a booking, a new code will be generated -- remember to send the updated code to the guest!
Canceling Codes: Igloo and ResortLock does not support canceling codes
Multiple Locks on one Booking: Each Igloo or ResortLock lock associated with the booking property will be programmed with its own unique code
