I had an unfortunate coffee spill on my MacBook and the keys got really stiff and crunchy. This was just what I needed to replace all the keys. Get to thin guitar picks to remove the old keys. Slide the pick under the bottom lip of the key, then carefully slide it to one side of the key. Then use a second pick to get under the other side of the key. Pry up with both picks simultaneously and they key should unsnap. Use a qtip and isopropyl alcohol to clean the hinge and then reinstall the new key. Tip the top end of the key in first then press down firmly on the front of the key to reattach.

Matches my MacBook, even though some keys didn’t stick well

It's impossible to tell which keys have been replaced. The backing did not match OEM so it's hard to say if these are OEM or not so it may be flagged during a repair but I find that highly unlikely; my OEM keys that were damaged also had different backings so it's likely just a difference in production facility.

Works as designed, no complaints, you cannot tell which keys were replaced.
