To check a smart lock’s battery, open the app for its exact brand and model and look for a battery status or alert; if the app has no battery screen, check the lock’s keypad or indicator lights and consult its manual. There is no universal battery percentage, alert threshold, or setting. Turn on alerts in both the lock app and your phone’s notification settings where supported, and replace batteries with the size and type specified for your lock.
How do I check my smart lock battery?
Start by identifying the lock model and the app it uses. Battery information may appear as a percentage, a status such as “Replace Batteries,” a push notification, or an on-lock indicator. Some locks do not show a numeric reading. App labels and paths can also change with software updates, so use the steps below as model-specific guidance and verify them against your current app and owner’s manual.

Schlage Home
For supported Schlage locks, open the Schlage Home app, select the Home, and tap the three-dot menu beside the lock to view its battery percentage. If the lock is not associated with a Home, scroll to “Unassociated Locks” and tap the three-dot menu beside it. Schlage says a critically low lock may flash a red battery icon before an action.

Yale Home
The cited Yale Home support guidance says the covered devices do not display a battery percentage in the app; they send battery alerts instead. A separate Yale Battery Insights feature can estimate remaining battery life on supported devices, but the estimate may change as the lock collects data. Check whether Battery Insights is available for your specific lock and app configuration. Yale Home battery alerts · Yale Battery Insights

How do I know when my smart lock batteries are low?
Use the lock’s own alert rather than a threshold you found for another brand. Manufacturer guidance shows that low-battery warnings can arrive at different levels and through different channels:

| Lock guidance | Battery information and warning | Other cues or behavior |
|---|---|---|
| Schlage Home | Battery percentage appears in the lock’s menu. Schlage Residential says the app logs a low-battery alert at 20% or lower and a critical alert at 8% or lower. | An on-lock touchscreen battery icon can also indicate low charge. These are Schlage-specific thresholds. Schlage alert guidance |
| Yale Home, covered devices | The cited support page says the app does not show a percentage and sends a low-battery notification at 25% capacity. If batteries approach end of life, Yale says daily emails and push notifications follow. | This procedure applies to the devices covered by that guidance; Yale Battery Insights is a separate feature for supported configurations. Yale Home battery alerts |
| Kwikset, cited families | The app can show “Replace Batteries.” For some Halo/Aura families, an icon appears at 20% and a tone at 10%; Halo Select guidance identifies both its low icon and tone at 10%. | Indicators depend on the specific model. Do not treat these figures as a universal Kwikset threshold. Kwikset battery guidance |
A low-battery warning is worth acting on promptly. Kwikset notes that low charge can cause delayed responses or connectivity trouble and may impair features such as auto lock/unlock, activation, calibration, or firmware updates. A lock may therefore behave unreliably before it stops operating altogether. Kwikset battery guidance
How do I turn on low-battery alerts?
Alert options differ by model. First enable the relevant setting in the lock app, if it exists; then allow notifications for that app in your phone’s operating-system settings. An in-app alert setting cannot override phone-level notification permissions.

Yale Battery Insights, where supported
For the separate Battery Insights feature, Yale’s help article gives this route: app Settings, Lock Settings, then Battery Notifications. Enable or disable Low and Critically Low alert types as needed, and check the phone’s notification permissions. Yale says occasional operation through the app helps keep the reported percentage accurate; a manual thumbturn operation does not always send a battery update. These controls and behaviors may not apply to every Yale lock or app configuration. Yale Battery Insights

- Reliable Performance: Designed to provide stable power for compatible smart lock camera and Wi-Fi functions.
Other locks
If you cannot find a notification control, check the model’s manual or manufacturer support page. Some locks provide an automatic alert but no configurable schedule, while others rely partly on keypad or lock indicators.

- Check the owner’s manual for the exact battery size and chemistry required for your model. Do not assume that all smart locks use the same cells.
- Replace the set as directed, using fresh batteries of the specified type. For the Yale devices covered by its cited support guidance, Yale specifies four new AA alkaline, non-rechargeable batteries. Schlage recommends quality alkaline batteries for its electronic locks, and Kwikset recommends standard non-rechargeable alkaline batteries for the families covered by its guidance.

- After replacing batteries, check the app or lock indicator again. Follow any model-specific steps needed to refresh or clear its battery status.
If Yale still reports low battery after replacement
For the Yale devices covered by its support procedure, operate the lock three times through Yale Home over Bluetooth, or remotely through a Yale Connect Wi-Fi Bridge. A manual thumbturn operation does not clear those notifications. If the alert remains 24 hours after replacement and app-operated cycles, Yale advises contacting support. Yale Home battery alerts

Why does my smart lock keep saying the battery is low after I changed it?
- The app has not received an updated battery reading. Use the lock’s app or the model-specific refresh procedure rather than relying only on manual operation; Yale’s cited procedure, for example, requires three app-operated cycles for covered devices.
- The battery type or fit may not match the model instructions. Check the manual and replace batteries with the specified size and chemistry. Schlage cautions that other battery types may affect alert behavior.
- The alert may be a stored notification or status that needs time to update. Check the manufacturer’s instructions for clearing it; if it persists beyond the stated interval, contact the manufacturer’s support.
What can help reduce battery drain?
If charge seems to fall unusually quickly, check the door and strike plate for misalignment or friction. Kwikset says resistance can increase battery demand. Its support also notes that disabling lock sounds and lock LED status in the app can reduce consumption on the cited families. These are model-dependent options, so change them only if your lock offers them and you still want those features. Kwikset battery guidance
