Keys not working on Blackberry Bold 9000?

[jon]

Okay, so a while back the keys on my Blackberry Bold 9000 stopped working, so I put the hair dryer over the phone on really hot and they began to work again really well. After about 2 days, they've stopped working again and now I'm back to square one. I tried the 'oven' trick and put the phone in there for about 20 minutes on 70 degrees Celsius, but it didn't work :-( does anyone know how I can fix this because I really need the phone!
