It is not just the keys, but also the connection to the display. The underlying problem is the same: The connections are mady by "zebra stripes" which require constant pressure that is achieved with some kind of foam rubber. Over time this hardens and rows and/or columns of pixels will be missing from the display. Some keys as well, especially the top row. One HP-48SX that I have suffers badly from this issue. One must firmly press down on the bezel below the display in order to see all pixels and use the top rows of keys... Any repair attempt will only make things worse on the long run.
