Since I installed the Kwikset halo lock in my home, I have been reading and writing about various aspects and issues concerning the lock. 

In this article, we will delve into the crucial aspect of battery replacement for the Kwikset Halo Smart Lock, highlighting the importance of using the right type of batteries and providing a step-by-step guide to ensure a seamless replacement process.

Choosing the Right Batteries

Kwikset, a trusted name in home security, recommends using 4 standard AA non-rechargeable Alkaline batteries for the Kwikset Halo Smart Lock. This recommendation is based on extensive testing and compatibility assessments carried out by the company. 

But why Alkaline batteries? Let me explain to you the reason behind this recommendation.

  • Stable Voltage Output: Alkaline batteries maintain a stable voltage output throughout their lifespan, ensuring that your smart lock operates consistently without voltage fluctuations. It is being reported by a few users that Lithium ion batteries show full charge and then die all of a sudden. I am sure no one would want such a situation and perhaps that’s the reason the company recommends using alkaline batteries.

Now that we understand the importance of using functional batteries in Kwikset Halo lock for its smooth operation, let’s proceed with a step-by-step guide for replacing the batteries in your Kwikset Halo Smart Lock.

Once you’ve removed the cover, pull up the battery pack. The battery pack is where the power source for your smart lock resides.

Step 3: Replace the Old Batteries

Step 4: Secure the Battery Pack

After inserting the new Alkaline batteries, gently slide the battery pack back into its place. You should press it back until it clicks or locks securely. This ensures that the batteries are firmly in place and properly connected to the lock.
