Lock + Unlock Objects

You can use the Lock command to specify that you don’t want certain objects to move in your document. Locked objects stay locked when a document is saved, closed, and then reopened. As long as an object is locked, it cannot be moved. 

• Select the object or objects that you want to lock in place. To lock the objects, choose Object > Lock.
• To unlock an object, click the lock icon.
• To unlock the objects on the current spread, choose Object > Unlock All On Spread.

You can also use the Layers panel to lock or unlock both objects and layers. When you lock a layer, the positions of all objects on a layer are locked, and the objects cannot be selected.

Lock or unlock layers

Locking is useful for preventing accidental changes to a layer. A locked layer displays a crossed-out pencil icon in the Layers panel. Objects on locked layers cannot be selected or edited directly.

• To lock or unlock one layer at a time, in the Layers panel, click a square in the second column from the left to show (lock) or hide (unlock) the layer.
• To lock all layers except the target layer, choose Lock Others in the Layers panel menu.
• To unlock all layers, choose Unlock All Layers in the Layers panel menu.
