Mogul Keys Sticking as of Late

[lawilson2]

On the keyboard, I'm having the worst problems using the period, the left arrow next to it, as well as the option button. I have to press extra hard on them in order for them to work. Thinking that it might be a software fluke, I hard reset to no avail.

Is this something that the Sprint insurance at a store would look into? I'd hate to find a store, get it there, and then they tell me it's not a big deal. I haven't dealt with repair/replacement before so anything that you can share would be helpful. Thanks in advance.
