SwitchBot Lock Ultra
The SwitchBot Lock Ultra is a retrofit smart lock designed to automate your existing door lock without a full hardware swap. It aims to bring app-based access and smart-home convenience to doors that already have a compatible deadbolt installed. For shoppers who want smarter entry with less invasive installation, it sits in the practical middle ground between a basic lock and a full replacement smart lock.
Pros
- + Retrofits onto many existing deadbolts without replacing the whole lock
- + App-based locking and unlocking adds convenience for shared access
- + Works well for renters who want a less permanent smart-lock setup
- + Pairs naturally with other SwitchBot smart-home devices
- + Compact add-on design keeps the exterior door look mostly unchanged
Cons
- - Usually needs a separate hub for full remote control and voice assistant features
- - Battery-powered design means ongoing charging or battery maintenance
- - Fit can vary depending on your deadbolt and door hardware
- - Not as clean-looking as a fully integrated replacement smart lock
