Keyboard engraving voids the applecare warranty?

[mgnayim]

Does engraving letters of another language on the keyboard voids applecare warranty?

Can apple know if a certain MBP had been disassembled ??
because I am thinking disassemble my uMBP 15" and replace the engraved keyboard with a new genuine apple keyboard

I don't know if engraving voids the warranty. But on the keyboard replacement..well...

Don't mess anything up in the process.
