Son´s 2004 gto is locked

[chevybernie]

Hi.
Can anyone help me? Before half an hour my son has washed his 2004 gto. Then he started him . He came to me and said he thinks, that the battery will be come dead. The starter cranks with loss power. Then he closed the car by remote control. Now he would drive, but the car doors are all locked. First a car symbol was blinking, now it´s out. I tried to open with the key, but nothing. Maybe the lock cylinder is damaged? Then i tried it with a wire. Can get to the door lock pin, but i´m always slipping. Does anyone know, how we can open the car?

Thanks god. Car is open. I put WD40 in the lock cylinder and i could turn the key to open the door. Battery is totaly dead. Tomorrow i´ll buy a new one.
