Anything can be dismantled - it's the putting it back together again that
can sometimes be a challenge :-)
Are the modern mac keyboard shells 'welded' at the seams, then? Sometimes
it's possible to open such things with a dremel-like tool and then add
material to take screws and hold it together afterwards (BTDT with some
'sealed' PSUs), but not always - and of course it may be more trouble
than it's worth if a replacement is cheap/readily available...
I took two Mac wireless keyboards apart recently. One had a block of
keys inop following spill, the other was dead. Aha, thought I, I'll
take the membrane out of the dead one and fit it to t'other and make a
working one out of the two.
They're held together with screws and come apart fairly easily. Allen
key needed (2mm IIRC) but once I got them apart, the innards were
completely different (different board in different place, hence membrane
tails in wrong place), so I had to give up.

On my wife's [PC] keyboard, the membrane actually separates into an

Various holes on all three parts line up and fit over pegs in the
keyboard shell moulding to keep them in the right place.
I'm sure they're not all like that and some are physically glued
together, but it wasn't immediately obvious that this particular one came
apart until I tried.
 ISTR that Sinclair Spectrum ones were, for instance :-)
Yes, those Mac keyboards had separable membranes like that. But the
tracks are very fragile and any drink spill, particularly if it contains
sugar, wrecks them. They're also quite fragile and I try and avoid
getting finger oil on the bits where a keypress makes contact.
I've also stripped and reassembled several PC keyboards with similar
