The
CAPS LOCKkey
Enter! Small or large, as the case may be
ENTERis another key on the keyboard.CAPS LOCKis used to toggle case between lower and upper, or small and large.
Author's note: in addition, the injunction "Enter! Small or large, as the case may be" can be read as an invitation to enter text into the computer by typing it in, in the appropriate case (lower or upper).
I'll assist you - it's easy!
CAPS LOCKmakes it easier to type a string of capital letters, rather thanSHIFT.
I'm both lock and key
Lock is in the name, and a key is what you are.

$\begingroup$ hahaha. I knew it would be fast, so I raced to the character limit, and then edited a few more words in. Worth it! $\endgroup$– MattCommented Mar 24, 2016 at 17:16

I know this has already been answered correctly, but I thought I would add what sprung to mind when I read the title, maybe someone will find it interesting.

A cipher key
Enter! Small or large, as the case may be
A key can be small or large, depending on the circumstances. Eg. a user's password to decrypt their hard drive, or an SSH keypair used to encrypt and decrypt network transmissions which is comparatively quite large.
I'll assist you - it's easy! - I'm both lock and key
The key(s) can be used to both encrypt and decrypt the information.

2$\begingroup$ This is what I thought of as well, especially when seeing only the title in the hot network questions list. $\endgroup$ Commented Mar 25, 2016 at 1:55

1$\begingroup$ "small or large": Cryptographic keys can be anywhere from 40-bit (export-controlled) to 128-bit (symmetric) to 2048-bit (recommended RSA) $\endgroup$– NayukiCommented Mar 26, 2016 at 3:37

$\begingroup$ As soon as I saw it in the HNQ, I thought "a symmetric encryption key". $\endgroup$ Commented Mar 27, 2016 at 10:10

As a perhaps tongue-in-cheek alternative:
Tom Hiddleston
Enter!
Tom plays Loki, and who can make an entrance to rival Loki's? Nobody! So much so that there is, in fact, a LEGO/Marvel computer game called A Loki Entrance. Because it's a pun, you see, on "low-key".
Small or large, as the case may be
Loki is a frost giant. That's fairly large. He can also become human sized.
I'll assist you - it's easy!
He's a helpful guy, whether you are a big famous reporter, unicef, or just a kid
I'm both lock and key
Loki contains "Lok" and "ki".
Who am I?
The question requires it be a who, not a what, and therefore cannot be the caps lock key! :D

Because,
Yog-Sothoth knows the gate. Yog-Sothoth is the gate. Yog-Sothoth is the key and guardian of the gate. Past, present, future, all are one in Yog-Sothoth. He knows where the Old Ones broke through of old, and where They shall break through again. He knows where They have trod earth's fields, and where They still tread them, and why no one can behold Them as They tread.
