Because the people there don't wanna be invaded, like at the goldenrod radio tower.
The Lavender Town Radio Tower is only accessible in the first floor in Pokemon HeartGold and SoulSilver. A security guard will tell you that after the takeover of the Goldenrod Radio Tower, they are stepping up security measures to prevent Team Rocket from hijacking their tower in Kanto.
You go to Lavendar City, and in the poke radio tower. Talk to a man in brown clothing by the elevator, and he'll give you the Kanto Radio Stations.Then you go to Snorlax. Get on the radio stations, and go to the top of the circle and the poke flute music plays. Get out of the phone, and the music will keep playing. Click (Press A) on Snorlax, and he'll wake up! CATCH IT!
Wake up the snorelax in front of diglett cave with the pokegear upgrade from kanto radio tower, then go through there.
when you go into the tower there will be a few people. ask each person and a guy will give you an app for your radio. otherwise, if you try to get into the elevator a guard will stop you and say a gang is doing something up there. sorry!
