You cant because they dont want Team Rocket to get in there.
Go to the Lavender Town Radio Tower. Then talk to a man in the upper corner. He will give it to you. They go to where the Snorlax is. Open your Radio and slid the little do to the top of the screen. This will turn the Pokeflute on. Then talk to the Snorlax. It will wake up.
First, go to Lavender town and get your Pokegear upgraded by a man in the radio tower, then go to Vermillion city and run east to Snorlax. Tune into the upper part of your radio and it will be playing the pokeflute. This then wakes up the snorelax.
Go up all of the stairs in the Radio Tower until you reach the top floor.
You don't actually get the flute in the game. Go to the Radio Tower in Lavender Town and talk to a man and he will upgrade your radio so it can work in Kanto. Then read the sign near him. It will say that if you go to the upper dot, star, etc that you access the Poke Flute. That's how! (P.S. Snorlax will appear at Level 50.)~You don't get a pokeflute on heart gold or soul silver, you have to help fix the power plant in kanto, then you go to the radio tower in lavender town, the director will give you an expn card upgrade for your radio, then you'll notice that your radio can tune to a pokeflute station on the top part of the tuner, it works just like a pokeflute. I assume you're trying to get the snorlax by diglett's cave. Hope this helps.
The upper part of the Radio Station is made accessible later on in the game whilst fighting Team Rocket
you get the new expn card from the man in the radio tower in lavender, after repairing the powerplant. then you go to snorlax (big fat pokemon) go to your pokegear radio. go to the upper part of the circle/panel and the pokeflute will start to play. *bam* battle! *WARNING* snorlax is level 50.
You don't actually get it instantly from a person. You gotta get the Kanto Radio Card. then, if you want to hear it, put the dot thingy on the upper right of the pokegear radio.
The SILPH SCOPE is an item used to see the Pokemon "GHOSTs" in POKEMON TOWER (which is located near the entrance of LAVENDER TOWN) that appear randomly in the upper levels of the tower. You will need the SILPH SCOPE to reach the highest level of POKEMON TOWER. This item is fairly easy to obtain, as long as your Pokemon are in good health and can successfully protect you. And that, my fellow Pokemon fan, is why you need the SILPH SCOPE.
When you first get there, ignore it. It is part of the plot later in the game. When you get to Lake of Rage, battle the red gyarados. When you exit the lake, you will be greeted by Lance the Dragon Master. He will ask for your help in beating Team Rocket. It's in the basement of the house above the Pokemon center. When you are done with this, you will get a call asking you to return to the city with the radio tower. At thispoint you will be able to get to the upper floors, but only while battling team rocket the whole way up. After you have defeated Team Rocket in the radio tower, the whole tower will be open for you to explore. **Make sure to talk to everyone in the radio tower after defeating team rocket. Two or three of them give you items as a thank you**
After returning the generator part to the power plant, go to the radio tower in Lavander town, talk to the guy in the brown suit and he'll give u the radio card EXPN. after u get it, go to your radio, take the little blinking white dot, and drag it to the center star at top. its not a item its in the pokrgear, click on the radio, then move the circle up in the middle in the center. You can get to the PokéFlute channel on your PokéGear once you've Kanto Radio stations. Manually move the cursor to the upper area of the touch screen radio, and exit. Talk to Snorlax and it should wake up however in order to get the Kanto radio stations added to your PokéGear you need to visit the Radio Tower in Lavender Town after you have completed the Machine Part quest.
