房客刚搬进四个月，交房租很及时，但为人很强势。最近偷偷重新配了钥匙没告诉我，被我发现后，又找各种理由，拖着不给l我新配的钥匙。想问坛里有经验地主，这事有什么办法解决？
租你的房子就没有隐私了吗？你这种房东招人讨厌。
比如你给两把钥匙，可是人家有tennager需要有多一把，为什么不能配呢？现在为什么要给你？人家还在用啊。
Pennsylvania tenants can change their locks, if not prohibited by the lease. Landlords may not unilaterally change locks as a form of eviction
让他自己去联系。我的一个房客也私自换锁，我说只要给我一把key就行。因为有emergency可以进来。
