Why does replying from the Lock Screen use the Apple keyboard?
Swipe a notification on the Lock Screen, tap Reply, and the keyboard that appears is always Apple’s own — a third boundary iOS draws, different from a secure field and different from Spotlight, because the phone itself has not been unlocked yet.
A message comes in while the phone is locked. You swipe the notification, tap Reply, and a small text field opens right there on the Lock Screen. Type into it and the keyboard is Apple’s own grey one — not whichever keyboard you actually use, not whatever sits first in your keyboard list, and with no globe key anywhere to switch away from it. It looks like the same trick a password field pulls, but the reason underneath is different, and it is worth knowing which one you are actually looking at.
A third boundary, not the two you already know
iOS keeps third-party keyboards out of two other places for two different reasons: a password field overrides your choice because that specific field asked to be treated as secure, and Spotlight never offers a choice at all because it is a system surface with no app behind it. Lock Screen reply is neither of those. The field genuinely belongs to Messages, WhatsApp, or whichever app sent the notification — it is an ordinary app text field, the kind a third-party keyboard normally has every right to draw itself into.
Why it happens anyway
What is different here is not the field. It is the phone. When that text box appears on the Lock Screen, the device itself has not been unlocked yet — you have not entered a passcode or been recognised by Face ID for this session. A keyboard extension is third-party code, and iOS does not load third-party code into anything drawn before that unlock boundary is crossed, no matter how ordinary the field behind it would be once you are actually inside the app. The restriction travels with the lock state of the phone, not with the app or the field, which is why it catches every third-party keyboard equally and why no setting inside any keyboard changes it.
How to tell which restriction you are looking at
- Keyboard reverts the instant you tap a login, payment or passcode field, then comes straight back the moment you leave it → the secure-field override. The phone was unlocked the whole time.
- Keyboard never shows up in the Home Screen search field, and there is no globe key there at all → Spotlight, a system surface, not an app.
- Keyboard is Apple’s own in a text field that visibly belongs to an app, appearing directly on the Lock Screen before you have unlocked → this one. The field is real; the phone just is not unlocked yet.
What actually helps
The short reply goes through exactly as typed with Apple’s keyboard — the message still sends, the recipient sees nothing different. For anything longer, or anywhere you want your usual sounds and theme, unlock the phone properly first and open the app instead of replying from the still-locked screen. The same notification is sitting in the app the moment you get there, with your regular keyboard available immediately, because you are now typing into an ordinary field inside an unlocked, running app rather than a field being drawn on top of a locked one. Replying to a banner that appears while the phone is already unlocked — from inside another app, or from Notification Center — is a different situation again: the phone was never locked to begin with, so it behaves like any other app field, your usual keyboard included.
Where Kibo fits
Kibo behaves exactly like every other third-party keyboard here, because this boundary belongs to the locked state of the phone rather than to anything a keyboard app can opt into or out of. Full Access does not change it either — Full Access governs what an extension can do once it has been loaded into a field, and nothing third-party is loaded into a field drawn on the Lock Screen in the first place. Open the app after unlocking and Kibo’s themes, sounds and lighting are exactly where you left them.
Frequently asked questions
Why does my keyboard disappear when I reply to a notification from the Lock Screen?
The phone itself is still locked at that moment, and iOS does not load third-party code into anything drawn before you have unlocked the device. It is not the field or the app refusing your keyboard — it is the lock state of the phone, and it applies to every third-party keyboard equally.
Is this the same restriction as a password field?
No, even though the result looks identical. A password field is an ordinary field inside an unlocked, running app that iOS overrides because it was marked secure. Lock Screen reply is an ordinary field too, but the phone itself has not been unlocked yet, which is a different condition entirely.
Will my usual keyboard work if I reply to the same message after unlocking?
Yes, immediately. Open the app once the phone is unlocked and you are typing into an ordinary field in a running app, exactly like anywhere else that keyboard already works.
