If you have had and used it for a long time, it’s happiness should be pretty high. If That is the case, then that is why you cannot release it.

A Pokemon with high Happiness cannot be released.

Go to Route 213. There is a small house on the beach. There, you will find Dr. Footstep. He will rate your Pokemon’s happiness.

If Snorlax knows an HM move nobody else in your box/party can know that is necessary to use ingame, that will happen.

Well you said it your self you used cheats to catch it so chances are its glitched.

codes always lead to problems. but if you tranfer snorlax to black and white and release it, there is a good chance, it will be gone.
