Few questions.
Has the laptop ever been dropped.
Or any liquid in a small amount been spilled on it.
A sticky liquid such as soda, or anything that contains sugar. ?
If the laptop is a Mini or 10.1" screen then the keyboards on them don`t last very long.
I have seen quiet a few fail after a year of use.
You can buy a new one from ebay and all the keys will work again. The membrane contacts wear out quickly.
So the matrix is broken leading to a loss of random keys.
The key board simply clicks out with a slight leaver and a new one can be replaced in a minuet or two...
