This works with any lock that supports remote code programming (Schlage, Yale, Kwikset, IDLock etc). You can see this post to compare lock models. It works with the standard SmartThings Z-Wave Lock and ZigBee lock device handlers. Click for the RLA FAQ's and guides.

IMPORTANT NOTES

• Clear all users from the lock before installing RLA or follow the "Clear Codes" procedure after you install RLA, on adding a new lock or if you need to reset all user codes on your lock
• Make sure your lock is no more than 20 ft from the nearest buffering repeater (the hub does not buffer)

3. Lock & Door Synchronizer
Keep your primary lock synchronized with secondary locks, doors, garage doors, relay/switch operated doors. You can synchronize them one way (primary to secondary or secondary to primary), two way or inverted (when one opens, the other closes). Mix match to suit your property needs, for e.g.:

• Create entry/exit corridor lock setup, a outside lock and insider lock, e.g.:
• Synchronize both locks to lock/unlock together when one is operated
• Enforce no piggyback, when one lock opens, the other closes and vice versa
• Set an exit door, when the inside lock unlocks, the outside lock unlocks but NOT vice versa
• Whole property management, lock/unlock all locks when the primary lock is operated
  
• Synchronize your patio door with your primary lock
• Synchronize your garage doors/gates with your primary lock
• Synchronize your keypad with a garage door (requires Enhanced Keypad Lock device handler)
• Unlimited combinations between multiple secondary locks, keypads, doors, garage doors, switches, relays and a primary lock:
• Two way synchronization
• One way -> Set primary to secondary
• One way -> Set secondary to primary
• Inverted -> Set secondary the opposite of primary
