Safety first! Before you begin, unplug the garage door opener from the electrical outlet. This will prevent any electrical mishaps while you’re working on the battery.

2. Locate the Battery Compartment

The battery compartment is typically located on the back or side of the garage door opener. Depending on the model, you may need to remove a cover to access the battery. Use a screwdriver to unscrew and remove the cover if necessary.

Plug the garage door opener back into the power outlet. Most LiftMaster models will automatically detect the new battery and stop the beeping. Some models may require you to reset the system or press a button to acknowledge the new battery.
