SwitchBot Lock Pro review
By Tom Calder
The broadest compatibility list here, built for British oval and Swiss round cylinders as well as standard euro-profile, and standard AA batteries mean no proprietary rechargeable pack to eventually replace. Its steady list price is competitive, though full keypad and fingerprint entry needs the separately sold Hub 2.
- Best for
- Buyers wanting the widest cylinder compatibility, including British oval and Swiss round, not just euro-profile, at the lowest starting price in this comparison.
- Skip it if
- You want fingerprint or keypad entry out of the box without buying a separate hub

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Confirmed compatibility with British oval and Swiss round cylinders as well as euro-profile, not just one door type
- Runs on 4 x replaceable AA batteries rather than a sealed rechargeable pack
- Works with Matter, Alexa, Google Assistant and IFTTT through a SwitchBot hub, sold separately
Worth knowing
- Keypad and fingerprint entry both require the optional SwitchBot Hub 2, an extra purchase
- No BS3621 or insurance-approval claim made by SwitchBot
- Promotional pricing with time-limited codes fluctuates, so don't bank on the discounted figure

Best for Homeowners who want to add app and PIN access to an existing UK cylinder lock without swapping out their current deadlock.

Best for Households wanting to replace their entire door handle with a keyless smart handle rather than just adding an actuator.
