The LiftMaster K010A0056 is the LiftMaster service reference for a 3V CR2450 lithium coin-cell battery used in select LiftMaster and Chamberlain remote controls and wireless accessories. Coin-cell batteries are common in compact accessories where a standard 9V battery would not fit.
A low CR2450 battery can cause poor range, slow button response, intermittent activation, or an accessory that works only when held close to the receiver. Since coin cells can look similar, the number printed on the old battery is the best confirmation.
Important: the uploaded row has a title/name mismatch because one field mentions CR2450 and another mentions CR2451. Stronger manufacturer references identify K010A0056 as CR2450. Verify your physical inventory label before importing this item live.

Compatible with select LiftMaster and Chamberlain accessories that specifically call for a 3V CR2450 coin-cell battery. Typical supported applications include:
Do not choose a coin-cell battery by diameter alone. Similar battery numbers can have different thickness, capacity, or contact fit, and the wrong coin cell can cause weak contact inside the accessory.
Battery replacement is low-voltage accessory work. If an access-control device still fails after installing the correct battery, check receiver programming and signal compatibility rather than bypassing any safety or access-control equipment.
LiftMaster references K010A0056 as a 3V CR2450 battery. The uploaded row contains CR2451 wording, so the physical inventory label should be reviewed before upload.
No. Even though both are 3V coin cells, the size and fit are different. Use the battery type called out by the accessory manual or the old battery label.
It is used with select LiftMaster and Chamberlain remote controls and wireless accessories that specify a CR2450 coin cell.
Manufacturer references list K010A0056 as discontinued with no direct LiftMaster replacement part, though standard CR2450 batteries may be available from battery suppliers.
Most remotes retain programming during a battery change, but a completely dead battery or old accessory may require testing and reprogramming after replacement.
