This is a set of the SwitchBot smart lock in black with an auto-lock function and a fingerprint authentication pad. I used it for about 3 months, but removed it because my child was playing with it. Batteries and double-sided tape are not included. The double-sided tape that was used has been removed with a special spray. There are no noticeable scratches, but please understand that this is a used item. All included accessories are shown in the first photo. Please check. Instant purchase is OK. - Brand: SwitchBot - Model Name: SwitchBot Lock - Included Accessories: Keypad, Instruction Manual - Color: Black - Features: Smart Lock Function
