You could simply say "my friend will not give me the keys." Alternatively, you could say "I did not receive the keys from my friend."

You could also resort to passive voice even though it sounds odd sometimes. "My friend told me that I would not be given the keys/ would not be allowed to have the keys" or even that "I would not receive the keys". Hope that helps.

To be honest, your English level is really so difficult to be understand just as if Westerners write Chinese articles those Chinese and I have to help them hardly correct for their exact meaning. If I talk about someone but I dont want the other know the gender of that person what should I say.. give examples for this situation please As my understanding is below: I told someone about that I don't want others know. I have told someone about that I don't want to let the other gender know with-formal- whom I am not unfamiliar (with) or who I am not unfamiliar with. Please check out your English dictionary directly for whom definition yourself- for my English dictionary is from Oxford 7th edition. I don't teach you English and I won't accept you is a respect if you don't choose me, either in return for my choice, but not because your gender or others. For key, you should escort females whether she is your friend or not ,or you may call police officer directly at risk to consider about yourself as well. In Asian, as you know, it is rare to hear female rapes male I have not heard until now, yet only annoying males they love so much, so don't worry about rape from Asian females apart from killing by knife or other chemistry. Good luck. The killer is "Not" me ....(^-^) ha~~Bless you well.
