Retrofit Smart Lock Tackles Tough Doors

Summary
- Lock Ultra retrofits most door locks, including jimmy-proof types.
- Adapter kit enables use with jimmy-proof and mortise locks.
- Offers smart lock convenience without replacing existing hardware.
The SwitchBot Lock Ultra, priced at $140, provides a smart lock solution adaptable to various door hardware. A $20 adapter kit extends its compatibility to jimmy-proof and mortise locks, a feature that sets it apart from typical retrofit smart locks. This makes it a rare, if not sole, option for smartening non-standard locks without extensive modifications.
The device attaches to the interior side of the door, offering smart functionality without altering the exterior appearance. While it requires a physical key or manual operation from the outside, it provides app-based control for unlocking. Users can also configure settings like auto-locking and receive alerts for prolonged unlocked states.
When paired with a SwitchBot Hub, the Lock Ultra supports Matter for integration with ecosystems like Apple Home. However, this integration was found to be unreliable during testing. The device features a rechargeable battery offering approximately one year of use per charge, with a backup battery to maintain basic functions during charging.
Optional modular keypads, such as the SwitchBot Keypad Vision, can add features like fingerprint and facial recognition. While these accessories enhance functionality, they also increase the overall cost, potentially rivaling complete smart lock systems. Despite some integration and authentication quirks, the Lock Ultra is a viable option for those seeking smart lock features without replacing their existing lock hardware.
