I can help you with that. Here are the steps to unlock your iPhone 5s:

1. Connect your iPhone 5s to a computer that has iTunes installed.
2. Open iTunes and select your device.
3. Click on "Summary" in the left-hand column.
4. Click on "Restore iPhone" in the right-hand column.
5. Wait for the restore process to complete.
6. Once the restore process is complete, your iPhone 5s will be unlocked.

Please note that restoring your iPhone 5s will erase all data on it, so make sure you have a backup before proceeding.
