Lock-On

Lock-On is a targeting mechanism in the Kingdom Hearts series, present in all installments except the original Kingdom Hearts: Chain of Memories. While the player will automatically attack the closest available target, Lock-On allows the player to permanently target a single enemy or attackable object, typically signified by the tan targeting reticule turning blue. While locked on to an enemy or an object, the camera will automatically move to follow the target.

Lock-On is activated and deactivated by tapping in Kingdom Hearts and Kingdom Hearts II, tapping  in Kingdom Hearts Re:Chain of Memories, double-tapping R in Kingdom Hearts 358/2 Days and tapping L and R at the same time in Kingdom Hearts Birth by Sleep. Switching targets while in Lock-On is done by pressing or  in Kingdom Hearts, by holding  and moving the right analog stick in Kingdom Hearts II, and by tapping R in Kingdom Hearts 358/2 Days.

In a number of games, there are abilities that assist or enhance the targeting and Lock-On features. These include Scan, Range Extender, and Auto-Lock.

Scan
Scan (ライブラ) is an ability that appears in Kingdom Hearts and Kingdom Hearts Final Mix, Kingdom Hearts II and Kingdom Hearts II Final Mix, Kingdom Hearts 358/2 Days, Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix, Kingdom Hearts coded and Kingdom Hearts Re:coded. It allows the player to view a targeted enemy's HP. In Kingdom Hearts its AP Cost is 1 and in Kingdom Hearts II its AP Cost is 2. In Kingdom Hearts 358/2 Days, Scan is found as an Ability Panel. In Kingdom Hearts Birth by Sleep it is a default ability.

While Scan is not available as an ability in Kingdom Hearts: Chain of Memories and Kingdom Hearts Re:Chain of Memories, Sora is automatically equipped with its effect.

In Kingdom Hearts Re:coded, Scan is also used to detect the backdoors that lead to System Sectors. Scan can be leveled up to LV 4 by linking more Bonus Boosters to CPUs. With each upgrade of the ability, Data-Sora's Backdoor Sensor is made more precise, and previously inaccessible backdoors are able to be found.
