I'm happy to help with this, Chan! If it is just the control panel that is locked, all you'll need to do is press and hold the lock button for about 3 seconds. This button is located in the bottom right corner of the control panel and has an icon of a lock. If your oven door is locked, this link (https://bit.ly/3mFAZfb) can walk you through what steps to take to get it unlocked. ^Jecca
