If the battery in your Weiser SmartCode 10 is dead and the keypad isn’t lighting up or working, you’ll need to replace the battery to restore its functionality. Here’s a step-by-step guide to help you:

1. Prepare the Batteries: The Weiser SmartCode 10 typically uses 4 AA batteries. Make sure you have four new AA batteries on hand before you start.
2. Access the Interior Assembly:
   • The battery compartment is located on the interior side of the door lock.
   • If there’s a cover, you might need to remove it to expose the battery pack. This can usually be done by unscrewing any screws holding the cover or simply sliding or snapping off the cover.
3. Remove the Old Batteries: The Weiser SmartCode 10 typically uses 4 AA batteries, depending on the specific model. Slide out or unclip the battery pack and remove the old batteries.
4. Insert New Batteries: Insert four new AA batteries into the battery pack. Make sure to align the batteries’ positive (+) and negative (-) ends correctly, as indicated on the battery pack. Slide or clip the battery pack back into its compartment.
5. Test the Lock:
   • After replacing the batteries, it’s a good idea to test the lock to ensure it’s functioning correctly. Press a few buttons on the keypad or use the lock/unlock button to ensure the lock engages and disengages properly.
   • If the lock has an LED indicator, it should light up when buttons are pressed, indicating that the batteries are working.
6. Replace the Cover: If a cover exists, snap it back into place over the interior assembly.
7. Monitor Battery Life: Most smart locks warn you when the batteries are running low, either through a flashing LED light, a beeping sound, or both. Make sure to change the batteries when you notice these warnings to ensure uninterrupted operation.

Remember, always refer to the user manual specific to your model for any nuances or specific instructions related to your lock. If you’ve misplaced the manual, you can often find a digital version online by searching for the model name and number and the word “manual.”
