How are we supposed to know that you can’t pair your lock? Your posts don’t say a single thing specific to pairing the lock with SmartThings. All you reference is creating a dummy lock and that you can only see lock and unlock which is because you selected the out of the box Device Handler from SmartThings.
Pairing your Lock initially with SmartThings has absolutely nothing to do with creating Device Handlers from @RBoy. After you successfully pair your lock with SmartThings and it selects the default SmartThings Device Handler then you can go down the route of adding / creating the Device Handler and SmartApp.
FYI from other Danalock v3 users (quick search in community posts) - Key when pairing “one meter away from hub”.
