Retrofit Smart Lock Tackles Tough Doors
1 Feb
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.
