HEANTLE A3-BBF Smart Deadbolt: 7-in-1 Unlock Methods for Convenience
But wait, there's more (because of course there is). Want to let the dog walker in while you're at work? Generate a one-time access code from your phone. Curious who's been coming and going? Check the real-time logs. And for those of us who can't remember if we locked the door (again), the auto-lock feature is a lifesaver.
- Fingerprint access so fast, you'll wonder if it even happened.
- Control it from your couch or your car—just add a WiFi Gateway.
- Auto-lock: because remembering is overrated.
- Installation? A screwdriver and five minutes are all you need. Seriously.
Bottom line: the HEANTLE biometric door lock is like having a personal security guard who also makes your life easier. Your family (and your peace of mind) will thank you.
