My blackberry 8120 keypad is not working key 4.5.6 is not working

Have your keypad checked out, I used to fix alot of blackberries and they suffered from defective keyboards, this seems to be a common problem with them. Replace the keypad under the keyboard, swap out your phone if you have insurance.

Good luck.
