This is a rather old question, but the solution might still be helpful to other readers.

I suggest you call Tech Support at Dell...

Several years ago, I worked on many Dell CPx 500 models in my work place. There was an issue that always involved a series of 4 or 5 keys (they were always the same keys) that would quit working and we had attempted to purchase new keyboards to fix the issue. It turned out, the real solution was to replace the 'motherboard' of the Latitude notebook!

Dell had knowledge about the keyboard/motherboard issue that we didn't know.

Does the keyboard from the C640 work good in the C610? Also, have you tried an external keyboard? Does it work good?

Wireless keyboard keys sticking

on most keyboad you can take of each key. Try to get a flat head screw driver and pop it of with some force. You then can clean the keys. If this does not work you might need a new keyboard. Do not use water (or very little)
