How We Picked the Best Smart Locks Under 100
We focused on the features that matter most at this price: reliable locking hardware, multiple ways to enter, installation requirements, connectivity, and practical access management. Models with fingerprint readers, PIN keypads, physical keys, Bluetooth, Wi-Fi, or mobile-app control can suit different households, so we considered both flexibility and ease of use.
We also looked for products designed around common US door setups, clear auto-lock functionality, guest-access options, and useful applications such as rentals or Airbnb properties. Before buying, verify the door measurements and confirm whether the lock requires a separate hub, a specific backset, or an existing deadbolt configuration.
Quick Comparison
| Feature | What to Look For | Best For |

| Bluetooth control | Local app operation without continuous Wi-Fi | Simple, lower-cost setups |
| Handle-equipped design | Integrated lever or knob replacement | Doors needing a complete hardware update |
Key Buying Factors for Smart Locks Under 100
Door Compatibility and Installation
Measure your door thickness, backset, borehole, and available clearance before ordering. A deadbolt replacement is usually simpler than a complete handle-and-lock conversion. Look for clear instructions and reversible interior components if your door opens in a less common direction.
Entry Methods and Backup Access
Fingerprint entry is convenient, while keypads make it easy to share codes without handing out keys. A physical key override or emergency power option is valuable if batteries run low or electronics fail. Choose at least two dependable entry methods for everyday peace of mind.
Connectivity, Battery Life, and Security
Wi-Fi models generally offer remote access and notifications, but may use more battery power or require additional setup. Bluetooth locks can be simpler and more efficient but usually work best when you are nearby. Check battery alerts, encryption and app support, privacy controls, and whether auto-lock timing can be adjusted.
Who Should Buy Which Smart Locks Under 100?
Choose a fingerprint-focused lock if you want fast daily entry without remembering codes. A keypad model is a strong fit for families, cleaners, contractors, and guests because access codes can be shared or changed easily. Select a Wi-Fi-enabled option if remote unlocking, activity alerts, or vacation monitoring matters. For rentals and Airbnb properties, prioritize temporary codes, app management, and a dependable mechanical backup.
Finally, buyers who want the simplest upgrade should choose a model matching their existing deadbolt. If the door also needs a new lever or handle, an integrated handle-and-keypad design may provide a cleaner installation, but it requires more careful compatibility checks.
