There are new keyboard-only replacement parts for sale, but using them requires melting off or otherwise removing the head of several plastic retaining pins, then figuring out how to re-secure them. That kind of replacement is beyond the scope of this guide, so we'll only be dealing with a replacement that comes with a keyboard + palm rest as a single unit as pictured above.
Outside of a malfunctioning keyboard, there are other possible reasons to replace this part. The palm rest is the foundation that all other components are mounted on, so there are many sources of damage possible. In the case of this particular repair, the mounting nuts for the hinges had been broken off, making it impossible to secure the display to the chassis.
