Interesting, a cup of sweet tea killed my A1243. Water got inside and shortened some pads or tracks, since pressing one key instead generated 3 or 4 others. I tried to dry it with rise and silica gel for weeks - didn't help. Then I tried to open it and that was an excellent example of an Apple product which feels great while it works and has 0 repairability, so is an e-waste when broken. Disassembly of any other keyboard would allow to fix such a simple problem. At the end I've got a used A1243 from ebay and am typing on it right now :) (if it breaks I would probably go to Logitech MX keys for Mac).

Yep, a splash of coffee is what finally did mine in and they’re totally unserviceable.

Fortunately low-profile keys have been growing in popularity in the mechanical keyboard community so there are some excellent options to choose from now.

During disassembly what surprised me the most was that the back plate is really rigid, since that plastic is reinforced with a metal plate. Instead of fixing that plastic-metal assembly with excessive use of glue, some 6-10 screws on the perimeter could produce the same solidity feel. Unfortunately much less repair-friendly and probably more expensive solution was used instead.

As a rule, screws are more expensive than glue for manufacturing.
