  "definition": "A wireline tool used to install a lock mandrel and its attached flow-control device into a specific selective landing nipple within a tubing string containing multiple nipples. The tool features keys that are retracted while running in the hole, allowing it to pass through shallower nipples. At the target depth, the keys are expanded to engage the profile of the correct nipple and set the lock.",
