# Do locks still work during an internet or power outage?

### Yes, you can continue to use locks during a power outage.

Your 33 Lock smart locks continue to operate normally during a network or power outage using all **previously programmed credentials**, including **PIN codes and access cards**.

These credentials will still **activate and expire according to their original schedules**, ensuring uninterrupted access for guests and staff.

**During an outage:**

- Locks continue working locally
- Existing credentials remain valid
- Remote access changes are unavailable

To add, modify, or remove access while offline, credentials must be **programmed directly at the lock** or created using an **offline passcode**.

Once connectivity is restored, the system **automatically syncs** and resumes full remote management.
