Keyless error or batt low??

[Blackyv]

ok, im driving a latio and just collected my car from workshop (due to accident..) a few days ago... so far, no weird sounds and everything seems perfectly done except for one weird phenomenon..... even with me on driver seat, and engine started and started driving, the "Key" signal will blink for around 10seconds and then gone... if no key detected, it's "red" and i cant start the engine but for this weird situation, key is detected and i can start engine and drive but the green lighted "key" sign will blink blink blink.... in fact, it seems no harm but it doesn't hapen this way before... is this the sign of weakening battery??..... come to think of it, 2yrs+ is about time to change the batt...
