SwitchBot Lock Pro Review: A Smart Retrofit Lock Worth $119.99?

Quick overview

The SwitchBot Lock Pro is SwitchBot’s retrofit smart lock — it mounts over your existing deadbolt without replacing your door hardware or requiring a locksmith. It’s rated 5.0 stars from 102 reviews on SwitchBot’s own site, one of the stronger review counts in the brand’s security lineup. We went through the product listing, specs, and bundle options to see what you actually get for the price.

Key features

  • Retrofit installation — an aluminum alloy casing fits over your current lock cylinder, so there’s no DIY hardware swap or drilling involved.
  • Auto-Lock and real-time notifications — the door locks itself automatically after closing, and the SwitchBot app sends status updates when paired with a Hub.
  • Up to 15 unlocking methods when fully combined — pairing Lock Pro with the Keypad Touch adds fingerprint unlock, passcode unlock, and NFC card unlock on top of app and auto-unlock.
  • Matter and voice assistant support — with a SwitchBot Hub 2 or Hub Mini Matter Enabled (sold separately), Lock Pro works with Apple Home/Siri, Google Home, and Amazon Alexa for voice-controlled unlocking.
  • 4 x AA battery power, rated for roughly 6–9 months per set (9–12 months with the optional SwitchBot Dual Power Pack), with low-battery notifications through the app.
  • Compact footprint at 120 x 59 x 83.9 mm and 435 g with batteries installed.

Who it’s for

This is built for someone who wants a real smart lock upgrade without swapping out their existing deadbolt or hiring a locksmith — the retrofit design is the whole selling point. Because voice control, remote/anywhere unlocking, and full app notifications all require pairing with a separate SwitchBot Hub, it’s really aimed at people who are willing to add that hub (or already own SwitchBot gear) rather than someone who wants a fully self-contained lock out of the box. If keyless entry via fingerprint, passcode, or NFC card matters to you, that also means budgeting for the Keypad Touch add-on rather than expecting it bundled in.

FAQ

Do I need to replace my existing lock? No — Lock Pro is a retrofit device that mounts over your current deadbolt cylinder using included mounting brackets and cylinder adaptors, so your original key-based lock stays functional.

Do I need a hub to use it? For basic auto-lock and app-based unlock at the door, no. But remote/anywhere unlocking, push notifications, and voice assistant integration (Apple Home, Google Home, Alexa) all require pairing with a SwitchBot Hub, sold separately or as part of a bundle.

How long does the battery last? SwitchBot lists 6–9 months on the included 4 x AA batteries, extendable to 9–12 months if you add the optional Dual Power Pack.

Can I unlock it with my fingerprint or a passcode? Yes, but only after adding the Keypad Touch accessory, which brings the total unlocking methods (app, auto-unlock, fingerprint, passcode, NFC card, and more) up to 15 when fully combined with Lock Pro and a Hub.

Bottom line

The SwitchBot Lock Pro is a solid pick if the retrofit angle is what you’re after — keeping your existing deadbolt while adding auto-lock, app control, and (with the right add-ons) voice assistant support and keyless entry. The catch is that several of its headline features depend on buying additional SwitchBot hardware, so it’s worth planning out the Hub and Keypad Touch as part of the real cost if you want the full feature set on day one. For a currently discounted retrofit smart lock backed by a full 5-star rating across 100+ reviews, it’s a reasonable place to start. You can check current pricing and bundles on SwitchBot’s site here.
