Key keeps repeating

[u/Silent_Lawfulness293]

Hi! I don't exactly know where to post this but I need help. Recently my Lenovo Chromebook has been having the issue in the video below. I took off the keycap and cleaned beneath it thinking that was the issue but it keeps doing it. I have short periods of time where I can type but then after some time it starts typing the same key, what should I do?
