Is there a way to get multiple locks set up for a single property? I am using remotelocks.
Yes, this is fully supported -- just set it that way in the property mapping in the lock settings in OwnerRez and the system will generate the codes appropriately.
You don't just have to map properties to locks one to one. You can map a single lock to multiple properties, or multiple locks to one property, and then when generating the code for a booking the system will look at the associated locks for the property and generate the appropriate code.
