Pressing digits while the lock is unlocked does nothing. Press the clear button to lock the lock after use.

Due to other known to you circumstances, your account is now Regular (again).
Thus judging this PR won't result in a rankup anymore.
In case that you want to rankup with this account later on, we can get back to it :)
