Laptop keyboard keys stop working randomly

Specs: Windows 7
I have a sony vaio vgn-cs320j and five keys on my keyboard stop working at random.  They are the space bar, caps lock, tab, esc, and colon. If a single one of them stops working they all aren't working and if one if them works all of them work.  The times at which they work or don't work seems pretty arbitrary.

Keyboards are a code maker device. That code is transmitted to the computer. I suspect that either a common line to those keys or a common part of the code chip is faulty. Most likely the keyboard since it is mechanical.
First step would be to test with known working replacement keyboard.

Why did it take me over a year to phone in a problem to ATT?
