Smart Lock batteries

For a longer battery life we recommend the Nuki Power Pack

Assuming an average of 8-10 locking operations per day, Nuki’s included alkaline batteries will last for about 4 months. When the temperature is very low, or the door does not work smoothly, or the latch is being pulled often (“open door”), then the battery life may be significantly shorter.
For a longer usage we recommend the Nuki Power Pack. The Power Pack is a powerful rechargeable battery pack for your Smart Lock ensuring an optimal power supply and battery life of up to 6 months.

How to change the batteries

At a power level of 20% Nuki will notify you via the Nuki app and directly on the Smart Lock via the LED signalization. So there is enough time to replace your batteries of your Smart Lock.
In case you are not able to change the batteries in time, the Smart Lock will not be able to receive any commands. However you can still use the knob or your mechanical key.

To replace the batteries, proceed as follows:



  1. The battery compartment is located on the bottom of the Smart Lock. To open it, press the small lever in the arrow direction and take the battery compartment out of the Smart Lock.
  2. Replace the batteries and insert the battery compartment back into the Smart Lock.


Battery type and durability

Nuki Smart Lock will automatically detect if alkaline batteries or rechargeable batteries are used. This optimizes the respective limits for the battery warning. You can also configure the battery type manually. Tap on the desired Smart Lock and enter the lock settings. Then go to "Features & Configuration" > "Battery" > "Battery type".

Please note that cheap batteries from discount stores will be depleted faster and the battery warning can be displayed shortly after the battery change.

Recommendation: Nuki Power Pack

With the Nuki Power Pack you benefit from an optimal power supply for your Smart Lock and battery life of up to 6 months. The Nuki Power Pack is compatible with every Nuki Smart Lock and can be easily retrofitted for your Nuki Smart Lock 1.0, 2.0 or 3.0.
Buy the Nuki Power Pack and power up your Smart Lock.
