I replace my battery and my keyboard is malfunctioning

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 :)!
