Smart locks are a great solution for those who frequently rent out their property or just fret over whether or not they locked the door on the way out. They oftentimes take serious effort to install, however. The SwitchBot Smart Lock solves this issue by fitting over and working with existing hardware. It attaches to the door using 3M adhesive, making it ideal for renters, and offers popular features like auto-lock, remote key sharing, and compatibility with voice assistants. Its simplicity also makes it one of the more affordable options on the market, and the battery lasts up to 180 days for added peace of mind.
