can model A1243 keyboards be disambled?

Keys can be removed (cleaned) without keyboard disassembly,

by gently lifting the top edge, inserting a jewlers screwdriver, and

slipping the 'edge-locks' in the corner... when re-assmbling, insert

the white plastic portion, and lock it, and press-on the outer key

pad cover.

There are no screws holding the device together; you must insert

a sharp implement between the lower plastic base and the metal,

and work it around to SPLIT the keyboard open. BIG NOTE: you can

insert (and split) from the bottom, and sides of the keyboard, but NOT

the top (thicker) edge. Doing so in this area may compromise ribbon

cables, etc.

Further dissasembly becomes more complicated. An inner metal

'waffle' like assembly can be taken appart by lightly drilling the tack-welded

points holding it together. Chances of destroying the board become highly

likely from this point on IMHO.

A quick google search for A1243 keyboard brings up many hits, including http://www.brunerd.com/blog/2009/08/25/apple-keyboard-a1243-disassembly/, which would have precluded your posting.
