To lock a Chromebook screen, press Launcher + L (the Launcher is the Search key on the left of the keyboard). On a touchscreen, tap the time in the bottom-right corner and then tap the lock icon. To unlock, type your account password or PIN, or use your fingerprint if you have set one up.
What You Need Before You Start
- Applies to: all Chromebooks and ChromeOS tablets, including Acer, Asus, HP, Lenovo, Samsung, and Google models. The steps are the same on every brand.
- Version: not version specific. The lock shortcut has worked the same way for years.
- Account: you unlock with your own account password, PIN, or fingerprint. If a school or work admin locked the device, contact them to unlock it.
How Do I Lock a Chromebook With the Keyboard?
The fastest way to lock the screen is the keyboard shortcut. It works on any Chromebook with a keyboard attached.
- Press Launcher + L at the same time. The Launcher (Search) key sits on the left where Caps Lock is on other keyboards.
- Your screen locks right away and shows the sign-in prompt.
If you hold the keys a little longer by mistake, you get the sign-out prompt instead. Tap the key combination quickly and release it.
How Do I Lock the Screen on a Touchscreen Chromebook?
On a ChromeOS tablet, such as a Lenovo Chromebook Duet, you can press the power button, but you can also lock it entirely from the screen.
- Tap the time in the bottom-right corner to open the quick settings panel.
- Tap the lock icon to lock the screen.
A short press of the power button does the same thing on most models. Hold it down and you get the power menu instead, so keep the press brief.
How Do I Lock the Chromebook Keyboard?
ChromeOS has no separate switch that disables only the keyboard. Locking the screen is the way to do it, because a locked Chromebook ignores every key press and every touch except the sign-in prompt itself.
- Press Launcher + L.
- The keyboard and the touchscreen are now inert. Nothing you press changes your work.
- Enter your password, PIN, or fingerprint to bring the session back exactly as you left it.
This is the right move when you hand the device to a small child, wipe the keys, or step away from a desk in a shared space. If you want a longer-term lockdown for a child, set up a supervised account instead, since that limits what can be opened rather than blocking input for a moment.
How Do I Freeze the Screen to Clean It?
There is no dedicated freeze mode in ChromeOS, and you do not need one. Locking the screen gives you the same result and protects your session at the same time.
- Press Launcher + L to lock the screen.
- Wipe the display and the keyboard. Stray touches and key presses do nothing while the device is locked.
- Unlock when you are finished.
Avoid closing the lid to clean, because on many Chromebooks that suspends the device and a stray press on the trackpad can wake it again.
How Do I Unlock My Chromebook?
Unlocking uses the same credentials you use to sign in.
- Press any key or tap the screen to wake it.
- Type your account password, or enter your PIN if you set one up.
- If your Chromebook has a fingerprint sensor, touch it to unlock without typing.
How Do I Make the Chromebook Lock Automatically?
You can have ChromeOS lock itself whenever the lid closes or the screen goes to sleep, so you never have to remember the shortcut.
- Open Settings.
- Choose Security and Privacy, then Lock screen and sign-in.
- Enter your password when asked.
- Turn on Show lock screen when waking from sleep.
How Do I Control Media From the Lock Screen?
ChromeOS lets you view and control whatever is playing, such as Spotify, YouTube Music, or a podcast, without unlocking. The card only appears while something is actively playing.
- Start playing audio or video from any app or tab.
- Lock the screen with Launcher + L.
- A media card appears with the title and play, pause, and skip controls.
- Tap the controls right on the lock screen. You do not need to enter your password first.
If you do not see the media card, make sure something is actually playing. The card disappears a few seconds after playback stops.
Frequently Asked Questions
What is the Launcher key on a Chromebook?
The Launcher key, also called the Search or Everything button, is on the left side of the keyboard where Caps Lock sits on other laptops. It opens search and is used in many shortcuts, including Launcher + L to lock the screen.
Can I lock the keyboard without locking the screen?
No. ChromeOS has no setting that disables the keyboard on its own, and no reliable extension does it either. Locking the screen with Launcher + L blocks the keyboard and the touchscreen together, which covers almost every reason people ask.
Why can’t I unlock my Chromebook?
If your password and PIN do not work, the device may be managed by a school or workplace. Contact the administrator, since only they can unlock a device they enrolled.
Does locking the screen close my apps or tabs?
No. Locking only hides your session behind the sign-in prompt. Your apps, tabs, and downloads keep running and are exactly where you left them after you unlock.
Wrapping Up
Lock your Chromebook with Launcher + L or by tapping the time and choosing the lock icon, and unlock it with your password, PIN, or fingerprint. The same shortcut is the answer when you want the keyboard and touchscreen to stop responding, whether you are cleaning the device or handing it to someone for a moment.
