Acer Aspir one model NAV50

[hmd]

The letter N on my keyboard won't work and it's in my access password - so I can't get into anything! Is there an external keyboard that I could use?
I have taken the key off cleaned the keyboard etc and N is the only one not working
I have tried pressing an holding the lower left of the key and every other angle!
I just would like to know which external keyboard I could use if any!
Thank you

You should be able to turn off the laptop, plug in an external, regular computer USB, keyboard and access it that way.
