How to tell if my keyboard was replaced with the new 2019 version?

I have a 2018 MacBook Pro which I took back to have the keyboard replaced the same week the replacement program was announced and perhaps a week after the 2019 MacBook pros were revealed with the new keyboard.

They repaired the keyboard without issue and assured me it was the newest replacement part however for some reason I am doubtful. Perhaps just out of skepticism.

What I'd like help with, is knowing if there is a way to tell if the new keyboard has been installed in my Mac or if it is of an earlier variant which has been proven to fail?

There is a serial number on the repair order which I assume will help determine an answer but perhaps there's something in the system info as well.

Does anyone have guidance for me regarding this or some way I can tell without opening the Mac up?

Apple has stated the older 2016 & 2017 models will be only getting the same keyboard they had originally as the uppercase is physically different from the newer 2018 model. The 2018 and 2019 versions of the keyboard are interchangeable per Apple and once the 2018 spares are used up the 2019 versions will be used.

So lets tear this down a bit... Apple and their service partners have spares stocked up so if you went in the next day of the announcement the probability is you would get the 2018 version of the part as the newer version spare would not have been shipped yet. Remember this was on the same day of the newer 2019 model!

In iFixit’s report on what was changed between the 2018 & 2019 models Fourth Time’s the Charm? Apple Changes MacBook Keyboard “Material”. The only visible change is the blister dome’s plastic is a different formulation (a bit more cloudy Vs the older version) and a very slight change in the metal dome.

Frankly, I don’t see these alterations as being the solution. In my opinion the issue is the hinge point of the butterfly thats the weak link and micro arcing within the contacts them selves. Without talking with the Apple engineers I can’t tell you if either of these more likely areas where even looked at, or if there was changes made.

I don’t recommend trying to check this out as the clips on the keycaps are very easy to snap off just trying to take them off. Once broken they can’t be put back on.

For now you’ll need to depend on Apple replacing it again if it fails again. Try not to use the A, S or E keys as they tend to be more used. Or, look at getting an external keyboard.

I’ll take that as an “I don’t know”.

@robertofeltit To be clear - Logic tells us you got the older 2018 keyboard. And you'll end up breaking it if you try to find out.
