What do you mean by "exit key interrupt"? I don't know the STM32F4 that
well. So please give some more details.

I would expect that either only specific interrupt sources can wake up
the processor from a deep sleep mode or that you can configure which
peripherals are still active. If your "exit key" is a GPIO line with
interrupt capability you should have a look at whether the module is
still active.
