Access code, what access code?
The BAe146, at least in Australia has no access code, no key access, and unless the wiring has been changed since I last flew one (2005), if the one electrical bus that powers the door release mechanism is un-powered, as when on emergency power, the door can't be opened except by one of the pilots leaving their seat, assuming they're not incapacitated, and opening it from the flight deck side.
