Gandalf only gives Thorin the key and the map (they go together) because they are rightfully his( being given to Gandalf by Thorin's relatives).
Moon Runes are the hidden text on Thorin's ancient dwarven map.
The moon
There were moon runes in the map. The could only be read by moonlight, and it could be only the moon in the same phase or same night. The runes told how to find the keyhole to the secret passage.
He had to supply the key that came with the map of the Lonely Mountains from the beginning of the book.

Gandalf is worried that Smaug may become an ally to the newly returned Sauron.
Gandalf had met Thorin's father. He gave him a map and a key that his father wanted him to have.
I'm not sure what you mean. Thorin's grandfather never gave Gandalf a mountain. As far as I know, Thorin's grandfather (Thror) died in Moria without ever meeting Gandalf. Gandalf did meet Thrain, Thorin's father, in the dungeons of the Necromancer and Thrain did give Gandalf a MAP of a mountain. And if your question is what is on the mountain on the map that Thrain, not Thror, gave Gandalf, in my edition of the Hobbit, it's a small picture of a dragon. Some of the spurs of the mountain also look like they're on top of it, but it's just a bird's eye perspective.
At the unexpected party, Gandalf gives Thorin a map of the Lonely Mountain, which has information about a secret door and the key to the secret door.
We are not told how he got out of the prison. It could be that he was just a visitor there when he encountered Thorin's father. We do know that he left with the map and the key.
The moon letters brought out additional information. Elrond found them while looking at the map with Gandalf and Thorin one evening. They provided information on the secret passage.

Gandalf gave them many things. The two actual objects were a key and a map. He also provided them with a burglar.
On the map on the frontpiece, Thorin's Map, there is a little bowtie at the southern side of the mountain. This represents the door that the dwarves fortified and then lead their assault from. It can be presumed that Thorin would have died not too far south of that point.
"There is one point that you haven't noticed," said the wizard, "and that is the secret entrance. You see that rune on the West side, and the hand pointing to it from the other runes? That marks a hidden passage to the Lower Halls." The Hobbit JRR Tolkien
