Smart locks used to mean dropping $200+, but 2026 brings reliable picks for about $100. Daniel J. Whitman tested dozens to find the best budget models that still guard your door.
Top Pick: TP-Link Tapo DL110
The Tapo DL110 lands at $150 (often on sale for less) and nails the basics:
- BHMA Grade 2 metal housing rated for home and light commercial use
- Fingerprint sensor stores 100 prints, keypad, app and Bluetooth unlock
- Built-in Wi-Fi-no extra hub required
- USB-C rechargeable battery lasts about a year
The only hiccup: you pull the battery pack to recharge, so keep a USB-C cable handy.

Toughest Option: Ultraloq U-Bolt Pro
Need maximum strength? The $180 U-Bolt Pro earns BHMA Grade 1-the same rating found on many commercial doors. A compact front sensor reads prints in under a second, while the interior module hides Wi-Fi radios and four AA batteries. It works with Alexa, Google and IFTTT, plus sends temporary eKeys to guests.
Apple-Friendly Pick: Aqara U50
Apple households on a budget can grab the $150 Aqara U50. It keeps HomeKit and Matter support, so you can tap to unlock with an iPhone or Apple Watch. The lock auto-locks, offers quiet mode, and uses four AAs. You’ll need an Aqara Zigbee hub for Wi-Fi remote control, but keypad and Bluetooth work out of the box.
Retrofit Choice: SwitchBot Smart Lock
Renters who can’t swap hardware love the $100 SwitchBot. It sticks over your existing deadbolt in minutes-no screwdriver required. Timers, auto-lock and sharing controls run via Bluetooth; add a Hub Mini for voice control or Hub 2 for Matter. Expect shorter battery life, but replacement is tool-free.
Cheapest Full Lock: Wyze Lock Bolt v.2
Wyze returns with the $80 Lock Bolt v.2, adding a physical key slot to the original keypad/fingerprint combo. Two AA batteries last up to 8 months, the Wyze app stays simple, and you get IP53 weather sealing plus BHMA Grade 2 security. No Apple support, and recent security breaches have been addressed, according to News Of Los Angeles testing.
