Can I replace "remain" to "keep"?

SpiderMan is reciting the American "Miranda Rights" here, so "remain" cannot be replaced with "keep" due to its legal context. However, in most other cases you can replace "remain" with "keep" or "stay." Ex: Remain silent. -> Keep silent. Ex: The piano will remain at my house. -> The piano will stay at my house.
