Problem Description

All previously enrolled fingerprints on your Wyze Lock Bolt were deleted after the lock automatically installed a firmware update overnight. The lock no longer recognises any enrolled fingers and the Wyze app shows zero fingerprint entries even though multiple fingerprints were enrolled before the update. Firmware updates on the Wyze Lock Bolt occasionally reset the fingerprint sensor calibration database as part of security improvements to the biometric storage format.

Symptoms

  • Lock shows 0 fingerprints enrolled in Wyze app after firmware update
  • All family members fingerprints no longer unlock the door
  • Lock updated overnight and fingerprints stopped working the next morning
  • Wyze app confirms firmware updated successfully but fingerprints list is empty
  • PIN codes still work after update but fingerprints are gone
  • Same fingerprint deletion happened on a previous firmware update

Recognize these? Here's what usually causes it.

Common Causes

  • Firmware update changed biometric storage format requiring data migration
  • Automatic firmware update ran overnight deleting fingerprint calibration data
  • Firmware security patch reset the secure enclave where fingerprints are stored
  • Fingerprint database incompatible between old and new firmware versions
  • Lock lost power mid-update corrupting the fingerprint storage partition
  • Wyze cloud sync did not back up fingerprint templates before update

Most fixes happen in the first 3 steps.

Warning

Do not interrupt power to the Wyze Lock Bolt while a firmware update is in progress. The lock's battery LED indicator shows a specific pattern during update. Interrupted updates corrupt the firmware storage and can brick the lock requiring a warranty replacement.

Step-by-Step Solution

1

Verify the Firmware Update Caused the Deletion

Open the Wyze app and tap the Lock Bolt then Settings then Device Info. Check the firmware version currently installed. Compare it to the version that was installed the last time fingerprints worked. If the version number changed since fingerprints last worked confirm this is a firmware-caused deletion. Check the Wyze community forum or app changelog for the update version to see if other users reported fingerprint loss with the same update.

2

Re-Enroll All Fingerprints

Go to the Wyze app and tap the Lock Bolt then Access then Fingerprints then Add Fingerprint. For each person enroll their primary finger by placing it on the sensor 8 to 10 times capturing the same finger from slightly different angles each time. Label each fingerprint with the person's name and which finger such as John Right Index. This volume of enrollment samples creates a rich match template that is more robust to the recognition variation introduced by post-update sensor calibration changes.

3

Disable Automatic Firmware Updates Temporarily

In the Wyze app go to the Lock Bolt settings then Device Info then Auto-Update and toggle it off. This prevents the lock from automatically applying firmware updates overnight without warning. Before each future update check the Wyze community forum and app changelog to see if fingerprint data loss is reported. If the update is clean re-enable auto-update. If fingerprint loss is reported wait for Wyze to release a corrected version before applying it.

4

Add Backup PIN Codes for All Household Members

After re-enrolling fingerprints go to the Wyze app Wyze Lock Bolt Access then Access Codes and add a numeric PIN for each household member. Backup PINs are unaffected by fingerprint sensor firmware changes and provide immediate access if fingerprints are ever deleted again by a future update. Store PINs in a password manager rather than written on paper near the door.

Report to Wyze Support

Submit a support request to Wyze at support.wyze.com documenting that the firmware update deleted your fingerprint data. Include the old and new firmware version numbers and the date the issue occurred. Wyze engineering uses these reports to identify firmware versions that cause data loss and prioritise hotfix releases. A documented user report can result in a rollback option or a corrected firmware version being released faster.

Quick Solutions

Re-enroll all fingerprints fresh after firmware update completes
Enroll each finger with 8 to 10 sample captures for best post-update recognition
Disable automatic firmware updates to control when updates are applied
After re-enrollment test each finger from 5 different angles before relying on it
Add backup access codes for all household members in case fingerprints fail again
Check Wyze community forum for reports of similar fingerprint loss for the update version

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.

Pro Tip

After re-enrolling fingerprints take a screenshot of the fingerprint list in the Wyze app showing the count of enrolled fingers. This documents the known-good state and helps you quickly identify if future updates have deleted data again.

Real-World Insight

Firmware updates that wipe settings are more common than brands admit — many devices silently reset to factory defaults on an OTA push with no warning.

What Usually Goes Wrong
  • Firmware update changed biometric storage format requiring data migration
  • Automatic firmware update ran overnight deleting fingerprint calibration data
  • Firmware security patch reset the secure enclave where fingerprints
  • Fingerprint database incompatible between old and new firmware versions
  • Lock lost power mid-update corrupting the fingerprint storage partition
