SwitchBot Lock & Keypad Touch Selling because I'm upgrading to a higher model. Both devices have been unregistered. I used both the Lock and Keypad Touch for about a year. Since they are located on the north side of the entrance and porch, I don't think there's any UV degradation. The Lock has some minor scratches. The keypad has no stickiness or worn-off letters. The batteries are also the same. They are currently working, but because they are security-related items, I cannot guarantee 100% functionality or provide compensation for any incidents. Please understand that they are being sold as junk items. Thank you for looking.
