If you use Face ID to unlock your iPhone X, you'll see an animated lock glyph on the lock screen that shows whether your device is locked or unlocked. When you jailbreak your iPhone, you can gain control over the lock glyph animation with LatchKey tweak.


What is LatchKey?

LatchKey is a free tweak that can customize the Face-ID Lock Glyph on iOS 11 – iOS 15 for Face ID Enabled Devices. It basically allows you to enable themes for the iPhone X’s unlocking glyph. On older devices, install Proudlock to enable LatchKey. XinaA15 Jailbreak is supported.

After installation, LatchKey tweak adds a dedicated preference pane to the Settings app from where you can toggle the tweak on and off and configure all options to your liking. Change the glyph appearance, and positioning. By default, it comes with 11 themes to choose from.

Here, you can customize the glyph positioning from Status Bar to Compact Status Bar (right), Compact Status Bar (left), Hidden, and Custom. Change the X and Y positioning by pixels, and modify the scale of the LatchKey glyph theme. There is also a toggle to hide the carrier name. The tweak works on modern jailbreaks for iOS 11, iOS 12, iOS 13, iOS 14, and iOS 15.
