Install the Nuki Keypad and open your Nuki Smart Lock with a 6-digit PIN code from now on. The keypad stores up to 100 PIN codes. You can also set temporary codes. This way, you can make sure the neighbors can get in during your vacation to water the plants, for example. Let the code expire when you get back from vacation, so you don't have to exchange keys. Is someone at the door who can't get in and doesn't have a code? Then connect the keypad to the bridge and add a new PIN code in the app when you're not home. This way, your children or guests will never be locked out again. The Nuki Keypad runs on batteries, so you don't have to install any cables.
