Hello, I recently change my Macbook Pro 13 battery with iFixit tutorial, everything went fine and i’m really happy from now. Just one small thing, my keyboard seems to malfunctioning some times. Some of my keys (lower bar with keys : w, x, c, v , b, n, , , ; , : ) are working then it’s not working anymore… It seems that they having some delays responding! Can it be due to the liquid I used to remove the thermal glue from the battery? Thxs for answering, My regards. ps : during the writing of this mail. The keys i mention bugged 3 times :)!

Sounds like the keyboard is liquid damaged, if you used excess liquid which got onto the back of the keyboard, this will be the cause. Leaving it to dry might resolve the issue (although it may reoccur in future), but it is best to replace it.
