Never store an electronic device for long periods of time with batteries! Over time, alkaline batteries will leak and corrode any metal parts in your toy. The reality of the situation is that most old used toys (e.g. on eBay) that are broken can be fixed by repairing the corroded pieces; many times, this is as simple as repairing or replacing the battery contacts/terminals.

Flip the toy over, so that the keypad is facing away from you.
Remove two Phillips-head screws.
Insert a plastic spudger (or 4!) into the marked holes, and push down and towards the edge to release each catch.
Separate the two halves of the case to expose the inner PCB, speaker and battery holder.
This is one of the worst possible cases of battery terminal damage.
The negative terminal was corroded badly, but could be cleaned enough to be usable.
The positive terminal had already decomposed entirely; there was no metal left, and the wire was just hanging loose.
The bus strip is clipped into the plastic case; it broke upon removal and needed to be recreated from scratch.
Time to get creative! We need a new bus strip to connect the two pairs of batteries in series.
The old, corroded terminals fell apart when I removed them, so I found some random scrap metal from another toy and made something similar in shape.
