After you get the Power Plant up and running, go to a guy with brown clothes on in the Kanto Radio Tower and he will amp up your pokegear. Go to the Snorlax blocking your way into the Diglett's Cave and turn on the pokegear. Go to the music section and put the beacon up until it says Poke Flute. Then talk to Snorlax.

You need to go through digletts cave. But first you have to wake up snorlax with the pokeflute that on the radio.
you need to catch or beat snorlax first but you 1st need to wake it up by playing the pokeflute on your improved radio

Digletts Cave is in Vermillion city although you have to go to Lavender Town to have your pokegear updated to have the poke flute music put on it.
Use the pokeflute in your pokegear from lavender town (go after you fix the powerplant and talk to the old man in radio tower) It's not programed, so you have to find it. Good lucks!
