Recognize these? Here's what usually causes it.
Common Causes
- Home Key pairing corrupted after iOS or watchOS software update
- Schlage Encode Plus firmware outdated causing NFC handshake failure
- Lock not added to HomeKit correctly during initial setup
- Express Mode disabled in Wallet app settings for the Home Key
- Metal phone case or watch band blocking NFC signal transmission

After regenerating your Home Key anyone you shared access with through Apple Home needs to be re-invited. Their Home Keys become invalid when you remove and re-add the lock.

Step-by-Step Solution
Update Schlage Encode Plus Firmware
Open Schlage Home app on your phone. Select your Encode Plus lock from the device list. Tap the gear icon for settings. Check for firmware updates and install if available. Wait 5 minutes for the lock to reboot after update. Outdated firmware is the number one cause of Home Key failures.
Regenerate Home Key by Removing Lock
Open Apple Home app on your iPhone. Find your Schlage Encode Plus lock and tap it. Tap Settings gear then scroll down and tap Remove Accessory. Confirm removal which deletes the Home Key from Wallet. Re-add the lock to HomeKit through Schlage Home app. When prompted add the new Home Key to Apple Wallet. This fixes corrupted Home Key pairing from software updates.

Open Wallet app on iPhone. Tap your Home Key card. Tap the three dots menu in top right corner. Ensure Express Mode toggle is turned ON. With Express Mode you do not need Face ID to unlock. Just tap phone or watch against the Schlage logo on lock.
Fix Apple Watch Home Key
If iPhone Home Key works but Watch does not the Watch pairing is corrupted. Open Watch app on iPhone and go to My Watch tab. Scroll down and tap Wallet and Apple Pay. Find your Home Key and remove it. The Home Key will re-sync to Watch from iPhone automatically. If that fails unpair and re-pair the Apple Watch entirely.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the keypad rejects valid codes, a lockout timer may be running — five failed entries locks most keypads silently for 5–10 minutes.
Hold your device against the lock for a full 2 seconds. Quick taps may not give enough time for the NFC handshake especially with Express Mode which still needs brief contact.
NFC Home Key failures after iOS updates are almost always a stale Wallet credential — Apple doesn't surface the re-add prompt, so users assume the lock is broken.
