Just an update on this matter. I mentioned before that I already changed the key fob's battery however, I kept on experiencing the "won't start problem and sometimes the door wont open too". Another thing I noticed though the battery was new, I saw a reminder at may dashboard KEY BATTERY LOW BAT. So I wonder why it indicates low-bat despite of just replaced remote battery. I checked the battery again and its still within the voltage rating. Lately I realized that the battery (button type CR2032) I placed into it is a generic battery you can buy in some Japanese store like Japan Home Center, DAISO, MINISO. This brand less battery has a low quality and could not sustain its charge considering that the remote is like a transceiver as you mentioned. So I decided to replace the battery with a branded one - Energizer. So far so good. Never experienced the problem again since then.
