Liftmaster K010A0025, BATTERY, 9V
The LiftMaster K010A0025 is the factory 9V replacement battery reference for select LiftMaster, Chamberlain, and compatible Craftsman wireless accessories. In the field, this part is most commonly associated with wireless keypads, older keyless entry products, and battery-powered accessory controls that use a standard rectangular 9V battery rather than a coin-cell battery pack.
A weak 9V battery can cause intermittent keypad operation, dim or missing keypad lights, reduced transmission range, lost programming behavior, or a keypad that works only when pressed several times. Replacing the battery is usually the first service step before replacing a keypad or accessory.
Fitment is battery-type based. If the accessory has a CR2032, CR2450, or other coin-cell holder, this 9V battery is not the correct style. Match the old battery shape, voltage, and the accessory manual before ordering.

Technician Note
If the keypad still does not respond after installing a fresh battery, inspect the battery clip, contacts, keypad membrane, and opener/receiver programming before assuming the battery is the only issue.
Before Ordering Checklist
- Confirm the old battery is a rectangular 9V battery.
- Check the accessory manual or battery compartment label.
- Inspect the battery contacts for corrosion or looseness.
- Do not substitute a coin cell for a 9V battery.
- Reprogram the keypad only if the accessory loses its stored code after battery replacement.
Professional Advisory
Battery replacement is normally a low-voltage service step. If the opener or gate system has additional electrical issues, have a qualified technician inspect the control equipment instead of bypassing safety or accessory wiring.
Important Ordering Warnings

- This is not a CR2450, CR2032, or other coin-cell battery.
