I'm using Maps pretty intensely and haven't seen a single fake business yet. Worst I've seen is single-person shops marking their home address as business location, I just report those as "private" through the Android app and move on. I'm sure the problem is there but it seem to only affect niche businesses and use cases. For locks in particular, just leave a backup key with your neighbor. It saved us multiple times over the years.
