Search warrant needed?

When the law recently passed on underage drinking parties, I heard some concerns about the ability of police to enter private households without a search warrant. I suspect scenarios like these cellphones with tracking devices may end up having an impact on the legal situation. That is, if a parent believes his/her child is drinking in someone else's house, can the police use the cellphones tracking device as reasonable cause to enter a house without a search warrant?
