Hi, I have a Toyota Aqua 2013 and it has been not moved for about 2 weeks now. However now the doors are not responding to the smart key. Replaced the key batteries but still did not work. The mechanical key is not able to open the door. the power shutters are also closed. i suspect that the car battery is also down but without opening the doors i cant get that fixed. please advise on what to do
