Hi all! I very much need help. My fiancé rebooted his MacBook Pro and I have no idea what he did. When turning on, it will go to the Apple logo and then the “no symbol”
It says the Macintosh HD is locked. I have no idea what to do. Halp pls

The "no symbol" doesn't exist. Is it "Prohibitory symbol", "Lock icon" or "Folder with a question mark" ?
More about the screens you see when your Mac starts up.

it is the prohibitory symbol that shows up when it is restarted
 
The prohibitory symbol usually indicates an issue with the hard drive or the installed system.

Can you boot into recovery mode by holding down command-R at boot?
 
Something went wrong with the system folder. Apple recommends reinstalling macOS. Do you have a backup?

I can boot into recovery mode but it will not let me reinstall the OS because the Macintosh HD is locked. If I go to disk utility, it can’t do anything with the disk (ie recovery/verify)
 
You are on High Sierra, right? Then press the View Button (top left) and choose to display all drives.
 
I understood the problem. With macOS High Sierra, the Disk Utility was changed, that's why I asked, if that was your installed macOS. I was talking about this.

By the way, I would have tried to boot into Safe Mode before going into Recovery Mode. (Press and hold "Shift" during reboot for entering Safe Mode).

EDIT: IMO, your image just shows that File Vault was enabled for your volume. It should get unlocked, if you were able to boot.

Hopefully this will give more of an idea of what’s going on.

If I try to go into safe mode, it will bring me back to the prohibitory symbol
 
If Safe Mode doesn't work, we excluded the small chance that just an incompatible Third-Party kernel extension prevented booting.
I don't give that much expectation, but you can try
1.) to reset NVRAM (press Option + Command + P + R for about 20 seconds during restart)
2.) If that still fails, try resetting the SMC: 1. Shut down Mac, 2. press Shift + Control + Option on the left side of the internal keyboard, then press and hold the power button for 10 seconds, 3. release all keys and start up normally (press power)
You didn't answer, if you have a backup and if you could toggle the View Button in Disk Utility to "Show All Devices". To know this is essentially for giving further advice to continue, if NVRAM and SMC reset won't work.
 
Your last image is even more weird, as it doesn't show any selectable Recovery partition.
You could enter your File Vault password then, but reinstalling means, all your data is definitely lost.
Do you want to get some data back from this Mac or do you just want to clean reinstall?

Honestly, I don’t care about the data at this point, i just want to the computer to turn back on

When you try to access a drive with FileVault enabled, macOS/Disk Utility will ask you for a password. This password is probably the same as your husband's login password. If you (or your husband) don't remember your FileVault password, it can be reset (if you allowed this option) via your AppleID account your husband gave it when he set up his user account.
