dropped it & now keys type the wrong letter

Hi,

I recently dropped my Apple wireless keyboard, it's the one that comes standard with the iMac (it's the A1314 model). Most of the keys still function properly, except for the numbers 1-9, & the keys Q-O. Every time I try to use them I get, both a letter & a number. For example, when I hit 1, it types q1, with 2 it types w2, with 3 it types e3, with 4 it types r4, & so on, 5 = t5, 6 = y6, 7 = u7, 8 = i8, 9 = o9, & 0 = 0. The same thing happens when I try to use any of the keys Q-P, with Q I get q1, etc. all the way through to O. Does anyone have any ideas as to why that is &/or if it's possible to fix it. If so, how. I saw the teardown of keyboard model A1225, but I'm not sure if that's helpful to me or not. I'm not very tech or fix it savvy. So, I may be in way over my head here, but I figured I'd see if there might be a way to salvage my keyboard.
