Tools & Requirements
Step-by-Step Solution
Check Battery Level and Recent Events
In the Ring app, go to Devices > Alarm Keypad. Check the battery percentage. The 2nd Gen keypad has a rechargeable battery that lasts about 9 months. If the battery is under 20%, heavy use (frequent arming/disarming, siren activation) may have drained it faster. Plug in the micro-USB charging cable on the back of the keypad to charge while troubleshooting.
Reduce Keypad Brightness
The backlit keys on the Ring Alarm Keypad 2nd Gen consume significant battery power, especially if the keypad is in a bright room and the brightness is set to maximum. In the Ring app, go to the keypad settings and reduce the display brightness. Also enable the auto-dim feature so the keypad dims when not in use.
Check for Firmware Updates
In the Ring app, go to Devices > Alarm Keypad > Device Health > Firmware. If an update is available, install it. Some firmware versions have battery management bugs that cause excessive drain. The update installs over Z-Wave from the Ring base station and takes a few minutes. Keep the keypad plugged in during the update.
Move Keypad Closer to Base Station
If the keypad is far from the Ring Alarm base station, it uses more power to maintain its Z-Wave connection. Z-Wave signal through multiple walls drains battery faster as the radio works harder. Move the keypad closer to the base station or add a Z-Wave repeater (like a Ring Range Extender) between them to improve signal.
Switch to Wired Power
If battery drain remains a problem, use the keypad in wired mode. Connect the micro-USB charging cable on the back of the keypad to a USB power adapter plugged into a wall outlet. When continuously powered, the battery acts as a backup during power outages and the keypad never needs manual charging.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Use fresh alkaline batteries from the same pack for consistent voltage.
App battery indicators run 15–20% behind actual charge levels — by the time the low warning appears, the device has been struggling for days.
- Weak Z-Wave signal
- Backlight set to always on
- Frequent arming events
- Old batteries
- Firmware outdated
