Print out a big image of your keyboard layout and hang it on the wall in your line of sight where you type. Never look at the keyboard, only look at the image on the wall. It won't take long to build the muscle memory this way.

A cardboard box:

And put stickers on your keyboard. Start with a few on the home row and gradually expand once you don't have to think about the location of the keys anymore.

When I was in high school I was playing WoW when Wrath came out. I was doing a lot of PUGs so there wasn’t any coordinated voice chat so I HAD to type in order to communicate, so that’s when I really learned to touch-type.

Every time you type a wrong key, hit that finger with a hammer. You'll only need to do it once or twice before you've terrified all the fingers into only ever pressing the right keys.

Playing a MMO.

You will learn where every button is. Or die trying.

In the 80's we had games to learn touch typing that were very helpful and also quite fun, compared to old school methods.
Here's a site that claims to have that sort of games:
https://www.typing.com/student/games

Warning I have no idea if these are good, it's just a random site a search came up with.

They make games where you have to spell words quickly or you lose and that's how I learned as a kid.

Like one where you're in a spaceship and have to shoot lasers at asteroids that are coming at your ship. You have to spell the word that's written on the asteroid to hit it with a laser.

Idk if any of them are free but they're basically simple coded flash games so I'm sure you could find one on the internet pretty easily

Good for you. I did not think typing was a skill that would be lost and so quickly. It boggles my mind they don't teach it in school now.

Mavis Beacon motherfucker!

I used to be a hunt-and-peck typist. For me, first you have to build muscle memory for key fingerings, which key is pressed by what finger. Then you can start to get faster. Building a strong foundation first.

I would have this site open on one window: www.keybr.com

And this image on another for reference:

KeyBR has “levels” where you work on a specific set of letters first, until you’re fast enough and they give you the next set of letters, adding on to what you’ve already done.

Once you’ve completed all letters, you stop progressing and just type words with all letters.

For me, after my first completion of keyBR, I spent a day or so practicing at the “endgame.” After that, I’d restart the entire module from scratch, back to the individual letters. Rinse and repeat.

After about a month or two, I was already touch-typing.

Then I got really into monkeytype.com, and started typing faster and faster.

The way I learned to type is by dividing my laptop screen into a left side, where I read, like the news, or Kindle, or some website I like, and a smaller right side that I don't look at, where I type into Word, or simply Notepad. I went from zero to 60 words a minute fairly quickly. I'm so used to it now that I like to type the books I read. It helps me also because I'm a diagonal reader. Typing what I read forces me to slow down and assimilate more of what I'm reading.

Typing of the Dammed?

My first recommendation is maybe consider a different layout. If you have been typing for long you will have muscle memory that will be hard to erase, I could mostly blind type (though not touch type) on qwerty, I decided to learn Colemak for touch typing and have never looked back. I still retain the muscle memory and can type somewhat fast on qwerty but after years of correct typing I notice just how bad what I was doing was.

IIRC I used https://thetypingcat.com/typing-courses/basic and trained on that and similar websites for a long time. You have to know that you will be very slow during a while and have to be prepared for that, but it does pay out in the end. While I didn't increased my typing speed significantly (70 to 85) it is a lot less strenuous on my hands.

I learned it by getting an a3 sized piece of light cardboard and a bit of string, hanging the cardboard around your neck so that it blocks the view of the keyboard, and then get a tool like https://klavaro.sourceforge.io/en/index.html for training (In school we used TippFix, an ancient Dos-based tool. Because this was a Computer Science School and we all were lazy fucks back then, someone in our class created a TSR Program which allowed people to simple hold Alt-Ctrl-LShift and it typed automatically and towards the end of the graded lessons we simply made 2 or 3 typos on purpose for plausible deniability, buy you also could simply edit the plain text files to contain rows consisting of a single letter. Made all lessons a lot quicker, which meant we could return to playing Command & Conquer, Nethack or MUDs sooner lol)

Just type stuff. Take a frequeent word you use, then repeat it until fluent.

A keyboard or a typewriter?

Get a keyboard with blanked keys, this is what I used

Your body learns real fast that looking down no longer helps with typing 👌

Honestly, just type a lot and try to get it done quickly. I never did anything specifically to try and learn, it just happened naturally following that for me.

I've heard people have a lot of success with various typing games, there's a few on steam now if that's your jam. Glyphica and The Typing of the Dead are the ones that immediately jump to mind

TypingMaster for PC was what I learned multiple keyboard formats. Now i use one on mobile and another for touch typing!

You can probably torrent it or just buy it but it has everything you'll need, you just need to do it everyday for 10-20 mins for a while. Helps to say the letters in you head maybe as you're typing. Like simultaneously mentally speak the letters as you press them

It gets easier as you move on to actual words and you learn to naturally chunk them together as you gain proficiency and fluency

If you're just getting started touch typing you may as well consider switching to a more comfortable layout like Dvorak for example before spending uncountable hours on learning qwerty
