A downhole shifter tool assembly configured to operate a downhole tool. The shifter tool assembly comprises a anchor tool, an extension tool, a shifting key, and a standoff spacer. The standoff spacer is configured to locate the shifter tool assembly at a reference position by contacting an isolation member on the downhole tool. An anchoring mechanism within the anchor tool can anchor the shifter tool assembly in the reference position. An extend-retract mechanism within the extension tool can extend move the shifting key on a shifting tool into engagement with a shifting profile on the downhole tool and move the shifting profile to a second position. The downhole tool can be operated by the shifting key moving the shifting profile from an initial position to the second position.
