How We Picked the Best Smart Locks Under 100
We focused on practical features that matter at this price: dependable keyless entry, installation requirements, access methods, app or Wi-Fi support, emergency backup options, and compatibility with common U.S. doors. We also considered whether each lock suits everyday homeowners, guests, children, Airbnb users, or rental properties.
Price can change, so verify the current total and included accessories before ordering. A low-cost lock is only a good value if it fits your door and provides the access method you will actually use.
Quick Comparison
| Feature | What to look for |
|---|---|
| Entry methods | Keypad, fingerprint, app, Bluetooth, physical key, or key fob |
| Connectivity | Bluetooth for nearby control; Wi-Fi for remote access and notifications |
| Lock style | Deadbolt replacements generally offer different fit requirements than handle or knob locks |
| Convenience | Auto-lock, temporary codes, activity logs, and one-touch control |
| Backup access | Physical keys, emergency power, or a secondary entry method |
Key Buying Factors for Smart Locks Under 100
Check Door and Deadbolt Compatibility
Measure the existing backset, door thickness, hole spacing, and interior clearance. A deadbolt model may not replace a knob or integrated handle, and some products require a specific latch configuration. Review the manufacturer’s fit guide rather than relying only on the product title.
Choose the Right Connection
Bluetooth locks are often simpler and may use less power, but they usually require you to be nearby. Wi-Fi models can support remote unlocking, guest management, and notifications, though they may require a hub, stronger batteries, and a reliable wireless signal near the door.
Prioritize Dependable Backup Entry
Fingerprint readers and batteries are convenient, but no electronic system should be your only plan. Look for a physical key, USB emergency power, or another clearly explained fallback. Also check battery type, low-battery warnings, and estimated runtime.
Consider Access Management
For families and rentals, individual codes, temporary passwords, access schedules, and activity history can be more valuable than biometric features. If you share access frequently, confirm whether those functions require a subscription or a specific app.
Who Should Buy Which Smart Locks Under 100?
For simple keypad entry: Choose a straightforward deadbolt or handle lock with reliable code access and physical-key backup.
For fingerprint convenience: Models with biometric readers are useful for households that want quick entry without carrying keys or remembering codes.
For remote access: Select a built-in Wi-Fi model if you need to unlock the door for guests, monitor activity, or manage access while away.
For renters and Airbnb hosts: Favor easy-install designs with temporary codes, auto-locking, and multiple entry methods. Confirm that installation will not violate lease requirements.
For cautious first-time buyers: A lock with keypad entry, app control, and a physical key provides a balanced mix of convenience and backup security.
