A scale is a series of eight sequential notes played in order, and the specific notes selected are part of a key. |
Not always, and not always. Most commonly used scales and modes have seven different notes (you're counting the tonic twice), but other scales have fewer or more than that. The specific notes do not have to be part of the key (harmonic or melodic minor scales, for example, are commonly used and have different notes than indicated by the key).

Keys rely on patterns. Look at your keyboard. From any piano key--black or white--to the next key is always a semitone. So from A to A# (# means sharp) is a semitone. From E to F is a semitone. Skipping one key--say from A to B without stopping at A#--is two semitones, or one tone. |
You're talking about intervals and scales, not keys.

Major keys follow this pattern, in terms of the distances between one note to the next. Whatever note you start on, follow this pattern and you will have a major key:
Tone - Tone - Semitone - Tone -Tone - Tone - Semitone. |
That's a scale, not a key.

To use the simplest major key--the key of C (keys are defined by the root, or the first note the key starts on), that gives you:
C - D - E - F - G - A - B - C
You'll notice that's played on all white keys.
Minor keys* follow this pattern:
Tone - Semitone - Tone - Tone - Semitone - Tone - Tone
The simplest minor key is the key of A, which gives you these notes:
A - B - C - D - E - F - G - A |
That's a scale, not a key.

(* there are different kinds of minor keys. The one we are talking about is the natural minor for simplicity's sake)

Natural, melodic, and harmonic minor are scales, not keys.

The formulas for keys are:
Major: TTSTTTS
Minor: TSTTSTT
|
Those are formulas for scales, not keys. The formula for keys can be found in your circle of fifths.

Knowing those patterns, you can now start anywhere on your keyboard, and build a key out of it. Once you have built a key--that is, once you know the notes you are going to use--you can then start fiddling around to build melodies within that key. |
Replace all those "keys" with "scales" and you'll start to get it.
