Is it safe to keep using?
Maybe. Regular baking and roasting do not require the door lock and can continue safely. Only self-clean is affected. If the door is stuck locked, do not use until released.
Can I reset the code?
Yes. Power cycle usually resets the lock. F7 will return when you try a function requiring the lock.
When to stop immediately?
