The c key on on my keyboard for the iphone 4 won't work how can i fix it?

Call apple and tell them but first try one of the following.

1. Plug phone into iTunes and back it up. Then shut the phone off. If that does not work try the 2nd option.

2. Reset iphone to factory mode. Make sure you back up your phone to iTunes before doing this step.

If all else fails call apple. They will talk to you over the phone and if they can't help you they will schedule and appointment for you to go to the apple store. They will give you options when you get there

You need a new digitizer (dead spot). They are about $70 to have someone install it professionally.
