I got my display key today and I was able to put the metal trim from my OEM display key to the aftermarket one. My key also has a cutout for the sim card slot even though it does not support any cellular functions. I have a feeling your display keys will have the same case as mine. Does anyone have the firmware for these keys? I want to get rid of the M logo on the lock screen. My computer reconsiders the key when turned off and eventually pops up as a USB drive.
