Changing the batteries in your Kwikset Smart Lock is a vital and straightforward procedure that helps to avoid being locked out and enhances the safety of your home.

Different models may require slightly different steps, but, overall, the process is generally straightforward and hassle-free. 

This article provides a comprehensive guide to changing the batteries in various Kwikset Smart Lock models, whilst highlighting some tips for improving the longevity of the batteries.

I recommend keeping an eye out for low battery indicators to avoid getting locked out. This is generally communicated via the keypad flashing red 10 times with 10 corresponding beeps.

Kwikset Battery Change Process

The process of changing the batteries in a Kwikset Smart Lock varies depending on the specific model you own. 

Essentially, there are two main types of these locks. 

  1. The first type comes with a removable battery pack and usually has a battery cover and an interior cover. 
  2. The second type requires users to load the batteries directly into the interior assembly, such as in the 264 Deadbolt, Powerbolt 2, or SmartCode 260 models.

To ensure a smooth and safe battery-changing experience, always have the door open and the latch in the unlocked position before you start. 

This precaution allows you to avoid any issues that may arise from accidental lock activation or potential malfunctions during the process. 

Instructions for Models with a Battery Pack

The following are instructions for the vast majority of Kwikset smart lock models including Kevo, Halo, Aura, Obsidian, Premis, and most SmartCode models.

  1. If the security screw was removed during installation, start by simply lifting the black battery cover to expose the battery pack. If the security screw is still in place, you'll need to first remove the interior cover. Locate the three screws on the left, bottom, and right of the interior cover and unscrew them. 
  2. Once the cover is detached, you can access the battery pack and lift it out using the small handle provided.
  3. Replace the old batteries with new ones, ensuring they are properly oriented according to the battery pack's markings. 
  4. After positioning the new batteries, insert the battery pack back into the lock. Remember to keep the door arrow on the pack pointed inwards towards the door, which is essential for the lock to function correctly.
  5. When the battery replacement is successful, your Kwikset Smart Lock will beep and emit a green LED flash. 
  6. This indicates that it recognizes the fresh batteries and is ready for use. 
  7. If you had to remove the interior cover, you can proceed with reattaching it. Make sure to align the turn piece with the turn piece shaft. If you didn’t remove the interior cover, then simply slide back on the battery cover.

With these steps completed, you have successfully changed the batteries on your Kwikset Smart Lock, ensuring its continued operation and security for your home.

Instructions for Models without a Battery Pack (e.g. Powerbolt 2 & SmartCode 260)

The following are instructions for models without a battery pack, including the 264 Deadbolt, Powerbolt 2, and SmartCode 260 models.

  1. Lift up the battery cover to reveal the batteries within the device's assembly. 
  2. Replace the old batteries with the new ones, taking note of the battery orientation.
  3. Before putting the battery cover back on, locate the reset button on the lock.
  4. Press the reset button firmly and hold it for around 5 seconds or until you distinctly hear three beeps.
  5. This step effectively resets the lock, eliminating any unwanted beeping. 
  6. Once you've completed this step, it's safe to replace the battery cover.

Keep in mind that during the entire process, the latch should remain unlocked to avoid any complications or difficulties.

Types of Batteries Required

When it comes to powering your Kwikset smart lock, choosing the right type of battery is crucial. 

Most Kwikset smart locks need four new, high-quality AA alkaline batteries to ensure optimal performance. 

Avoid using expired or rechargeable batteries, as these can result in slower response times, reduced operational capabilities, and unexpected deadlocks. Expired batteries have a diminished capacity, which reduces the lock's reliability, while rechargeable batteries have fluctuating voltages that can cause the lock to behave erratically.

The SmartCode 955, on the other hand, is an exception in terms of battery requirements, as it operates on a single 9-volt battery. So for those with a SmartCode 955, it's important to use a high-quality 9-volt battery when it's time for a replacement.

Door Handling Process

With most Kwikset smart lock models, you don't have to worry about performing the door handling process again when changing the batteries. So, there's no need to press the Program, Lock, or A buttons during this process. 

This makes battery replacement quick and easy without disrupting your smart lock's functionality. Just follow the instructions provided above when swapping the batteries.

Re-pairing Devices, Re-Enrolling Fobs, Resetting Codes

Changing the batteries on a Kwikset Smart Lock is generally a simple task that doesn't interfere with any connected devices, or require re-enrollment of fobs, or resetting of codes. 

The reason is that the smart lock's memory retains all the specific settings and information even when the batteries are removed. 

This means that you can change the batteries without worrying about having to re-establish connections or reconfigure anything in your smart home setup.

However, in case you need to perform a factory or network reset on your Kwikset Smart Lock, you will have to reconnect your devices and systems to the lock. 

Z-Wave / Zigbee Models

For Z-Wave or Zigbee smart lock models, it's recommended to wait at least 30 seconds after removing the old batteries before putting in the new ones. 

This short break lets your lock power cycle correctly. If the lock still struggles with joining or rejoining the Z-Wave or Zigbee network, take out the battery pack and follow these steps.

  • First, press and hold the program button for five seconds. 
  • Next, do the same with button A. 

This sequence of actions should fix any beeping issues that might continue after a battery change.

Ways to Reduce Battery Drain

A key concern for Kwikset Smart Lock users is preserving battery life. By employing a few simple tactics, it's possible to extend the life of your smart lock batteries without compromising their functionality.

In conclusion, changing the batteries in your Kwikset Smart Lock is a straightforward task that can be quickly accomplished by following the specific instructions for your lock model.

Ensure you use high-quality alkaline batteries when swapping them out and keep a regular eye out for low-battery indicators to avoid getting locked out.
