Blackberry Bold 9000 Letter Key Problem
 

before i go get this phone repaired i'd like to know if this is possible to fix on my own so i could save some cash.

my "A" letter key isn't working, whenever i press it, "uo" pops up so for example i try to type blackberry, it would write down as bluocberry. the green call button would type "jk" and red end button "nm".

this is how my phone is like right now.

my phone is on passlock so i can't do anything at all, not even do a handheld wipe since im not able to type down "blackberry"

is there any way you can fix this?

and since i don't have a warranty with this phone, i tried to disassemble it and get rid of all of the dust but nothing's working.
