Lots of trouble with mine as well. Key presses getting doubled or more. Especially on the "b" key. Had to replace the entire key and membrane and clean underneath the glued membrane to get it working again. (was 2 months out of warranty)

Also had the left command key just fall off. I know I rest my finger on it, but it shouldn't just fall off.

I like the low travel that some complain about, but any keyboard is useless if it doesn't work consistently.

Just FYI, some credit cards extend manufacturer warranties to two years, so may be worth looking into it. Also, which model do you have? Some non-TB 2016-2017 13" MBP are eligible for a free topcase replacement for battery issues.

It's the TB 15". I thought about seeing if I could go into an Apple store and see if I could get them to do it, but I am currently 2 hours away from the closest real one.

Thanks for commenting. I have the same problem with the "b" on my 18mo MBP.

Can you elaborate or link-to some more info on "replace the entire key and membrane"? Apple want to replace the top-case at AUD $650...

I didn't find any how to, so here is a bit of what I did:

Failed: compressed air

Failed: cleaning under the key.

Success:

Remove the key (careful, these keys really like to break the bottom u hooks)

Remove the butterfly

Peel off the glued membrane

Cleaned all with 90% alcohol.

Took a new membrane (you might be able to use old) and used E6000 glue and a toothpick to glue it back (don't get the contacts).

Replaced butterfly and key.

Not a good solution, but it worked.

I got the key, butterfly, and membrane from replacementlaptopkeys.com.

It looked like the contacts were getting coated/corroded and not making good contact? Perhaps heat?
