Switchbot Smart Lock Pro, brand new and unused. I prepared two sets, but only needed one, so I'm selling the other. The standard Lock Pro uses batteries, but I'm also including the separately sold rechargeable battery pack. (This has been opened. As shown in the photos, it only includes the battery itself, no other accessories.) If you plan to use this on your home door, please be sure to check the Switchbot official website to confirm that your thumbturn is compatible before purchasing. Please note that we cannot provide support for issues such as the product not fitting your door. Thank you.
