Obviously, one of the great enemies of any technological device is dust, grease and dirt in general. The only way to combat these elements is to simply clean our device from time to time. The problem is when it comes to a device with a keyboard, cleaning the keys can cause us to press things that we would not like. What can we do? As we can lock the keys of a MacBook to clean them? There are several options.

Imagine that we are concentrating on cleaning the keyboard, we open some other app and we accidentally send messages or emails, it does not seem like a good idea, right? In these cases, we will need to lock the MacBook keyboard to proceed to clean it without any negative consequences.

Obviously, this makes performing a good cleaning too complicated. Something that is generally recommended to do often to prevent dust from accumulating, among other things.

Use the lock screen to disable most keys

This gives us the possibility to clean our keyboard. The only thing we have to keep in mind is not to touch the Touch ID button with our finger or accidentally write the password. As long as we don’t do this, which isn’t too complicated, we shouldn’t have any problems.

One thing to keep in mind is that this will not disable the media keys. So if we press these keys we could be lowering the brightness or the volume. It is something minimal that we can later adjust without problems.
