How to Replace the Batteries

If your Kwikset SmartCode 910 lock is beeping, unresponsive, or the keypad is flashing red — it’s likely time to change the batteries. This guide walks you through the process clearly and confidently.

You may need to replace your batteries if:

• The keypad flashes red after entering a code
• The lock beeps but doesn’t turn
• The motor sounds weak or delayed
• The lock stops responding entirely

Tip: Replace the batteries every 12 months, even if the lock still works, to avoid getting locked out unexpectedly.

• 4 new AA alkaline batteries

Do not use lithium or rechargeable batteries

• Clean hands — no tools required

Here’s how to change the batteries in your Kwikset 910:

Remove the Battery Cover

• Locate the interior side of your lock (inside your home)
• Slide the battery cover upward until it comes off

You’ll see the battery pack inside the lock housing

Remove the Battery Pack

• Grasp the black plastic battery holder
• Pull it straight up and out of the lock

Replace the Batteries

• Remove all four old batteries
• Insert 4 new AA alkaline batteries
  • Match the (+) and (–) markings carefully
  • Use brand-new, non-rechargeable batteries for best performance

Reinsert the Battery Pack

• Slide the pack back into the lock the same way it came out
• Make sure it’s seated properly

Replace the Battery Cover

• Align the cover with the track
• Slide it downward until it clicks into place

• Test the lock by pressing the Kwikset button
• Enter your code to make sure it unlocks
• If the lock doesn’t respond, remove and reseat the battery pack to ensure good contact

• Keep extra AA batteries nearby for future replacements
• Never mix old and new batteries in the lock
• Don’t wait until the lock completely dies — low battery indicators are your early warning

According to the document image:

• The battery pack is located directly behind the interior cover
• Arrows on the cover show which way to slide it
• There are clear diagrams showing battery direction (+/–)

If you’re unsure, always refer to the label inside the battery compartment.
