You can either use the car keys to lock and open the doors or even use the car remote if you have one. The car horn will go back to normal in less than one minute or so. You are then able to start your car and move with it.
The battery might be dead and will probably need a replacement as trying it again and going for another will repeat the whole process all over. However, if you were just jumpstarting an old battery and this happens and you get the car alarm off, you will need to let the battery obtain charge first.
This is because the battery you have might have experienced a significant amount of drain and you will need to have it recharged for a while before using it.
