This will open Seam, the 3rd party software we use to connect locks. Follow the prompts to connect your lock with Host Tools. Seam allows us to automate Schlage, Yale, SmartThings, Nuki, TTLock, Kwikset, Igloo Home, and more locks. See here for a complete list of locks.
Once you have linked a Smart Lock account, you still need to link a lock to your listing to start automatically setting codes.
Note: Seam does not add codes to your lock until 72 hours before check-in.
