Before buying a smart lock, the first question isn't which model — it's which door. The wrong model on the wrong door causes problems after installation. Here are the criteria to consider when determining the right model for your door.
1. Door material
Wood, steel, aluminum, PVC, and glass doors each require a different mounting body and lock mechanism. For example, external-mount systems are more commonly preferred for steel doors, while glass doors use specially bodied models.
2. Door thickness and existing lock cavity
Smart locks are mostly designed to fit an existing lock cavity, but each model has a different compatible door-thickness range. Sharing a photo of your door — and its thickness, if possible — before installation speeds up the process.
3. How many entry methods do you want?
- Code: Requires no extra device, practical for family use.
- Card / NFC: Common in offices and building entrances, easy to manage.
- Fingerprint: Fast, personalized entry.
- Mobile app: Enables remote management and adding/removing users.
Models that combine several of these methods, matched to your usage habits, are usually the most practical choice.
4. Where it will be used
Home, office, hotel room, or gym — each setting has different priorities. Home use highlights comfort, office use highlights access management, and hotel use highlights centralized control.
The right model is determined as much by who enters, how often, and how, as by the door itself.
