Hey, can someone help me? My keyboard button 1,3,9 and # not functioning well. It needs to type a few times before detecting. This is abit irritative when i am smsing

i went to the shop and they say need to change the whole keyboard (after i told them what happen and they seem to magically know if it is not dirty or something and conclude i need to change) and it will cost me RM210 for the new keyboard .

Do u know where i can get this fixed? Anyone here know how? Or can recommend me a shop? I went to digital mall for this actually. I didnt have time to go to another store, cause the police was saman-ning lol

Thank you!
