What is the lock sound?

The lock sound is the audio that plays when you lock your iPhone. It's a short clicking sound that plays when you press the lock button on the side of your iPhone. Note that the lock button and the power button for turning off your iPhone are the same button. Did you know that you can also change app notification sounds? This is a great way to quickly know what app is notifying you!

Turning On/off the Lock Sound

Open the Settings app. It's a gray gear icon on one of your iPhone home page screens.

Tap Sounds & Haptics. This will open the Sounds & Haptics page in Settings.

Tap the toggle next to "Lock Sound." This will turn the lock sound on or off. The lock sound is on when the toggle is green and positioned to the right. You can also turn on or off the "send text" sound on your iPhone.

Troubleshoot issues with the lock sound. If the lock sound is turned on but not playing when you lock your device, there are a few things you can try to resolve the issue: Make sure your iPhone is in Ring Mode. Move the Ring/Silent switch on the side of your iPhone to the Ring position, so that there is not a red background behind it. Go to Settings > Sounds & Haptics and turn up the "Ringtone and Alert Volume." It's a slider near the top of the page. Toggle off "Change with Buttons" on the Sounds & Haptics page so that pressing the volume buttons doesn't change the ringtone volume. Now they'll only change the volume of app audio playing on your iPhone.
