March 15, 2025 - Usually you can re-add the default secure boot keys after deleting, no issue. But ymmv ... After making a backup of the PK and deleting it, it works. So that's the solution. It seems that maybe you will need to set up admin password, but after deleting the pk the secure boot gets disable.

r/ASUS on Reddit: Can’t disable Secure Boot again on Asus Vivobook 15 (stuck in Key Management lock)
August 31, 2025 -
Hi everyone,
I have an Asus Vivobook 15 laptop.
SN: S7N0CV07916628A
EC Version: F00D30C1.308
Running in UEFI mode.
I recently disabled Secure Boot to install Arch Linux. That part worked fine. Later, I needed to enable Secure Boot again (to play Valorant 🙄), so I turned it back on in BIOS.
But now I can’t boot into Windows 11 (or Arch, it’s not set up yet). I get this error:
"SECURE BOOT violation, invalid signature detected. Check Secure Boot policy in Setup."
So I tried disabling Secure Boot again by resetting Key Management to “Setup Mode,” but I get another error:
"Secure variable update is locked down. Try again after system reboot."
I rebooted several times, but it didn’t help.
Right now I’m stuck:
Can’t boot into Windows
Can’t disable Secure Boot
Can’t reset keys
I thought about just deleting the Arch partition and hoping Windows would boot, but that’s not really an option at this point.
Has anyone faced this issue with an Asus Vivobook before? Is there a way to force Secure Boot off or reset the keys without bricking the laptop?
Thanks in advance 🙏

usually you need to set a admin password to disable it. What I would recommend make a simple admin password remove it and then disable secure boot. This works because the BIOS just needs a admin password to be created once usually.
