Replace the keyboard. Check ebay out for a keyboard replacement. If you search some forums or contact dell they can tell you exactly how to do this. It usually involves taking off the lcd plastic hinges and removing the top strip where your power button is. One or two screws later and your there. It really isn't complicated.

This isn't your model, but most are similar.
