Guitars have tuning keys because they need to have a certain sound to make them sound good. Basicaly they need to be in tune.
Guitars are tuned by adjusting the tension of the strings to produce specific pitches. The standard tuning method for guitars is EADGBE, where each letter represents a string from the thickest to the thinnest.
Depending on the tuning, most guitars reach three full octaves. 20 Fret guitars in standard tuning should be able to play about 45 different half-tones.
The standard tuning note for the guitar is E.
The most standardize tuning for guitars both acoustic and electric is EADGBe(the lower note indicating this is the highest) with the A being at 440hz. This is only standard tuning and you can tune your guitar several different ways depending on what kind of music you are playing. My favorite open-tuning(tuning your strings to the note of an open chord such as G, Em, etc) is Em which is EBEGBe or E Maj which is EBEG#Be. For a fuller list of tunings, see trealted link.
Guitars are strung by attaching strings to the tuning pegs at the headstock and securing them at the bridge. The process involves threading the strings through the bridge, winding them around the tuning pegs, and tuning them to the desired pitch.
The recommended tuning for lap steel guitars used in country music is typically Open G tuning, which is D-G-D-G-B-D from low to high strings.

There are mainly two types of tuning pegs used on guitars: friction pegs and geared pegs. Friction pegs require manual adjustment and can be more challenging to tune accurately. Geared pegs have gears that make tuning easier and more precise. The type of tuning pegs can affect the guitar's performance by influencing tuning stability, ease of tuning, and overall playability.
The purpose of a tuning fork is to know the exact pitch of a certain note, and then tune to that note. The string is probably loosened to match the pitch of the tuning fork.
