Replacing a car battery on older vehicles used to be simple. You unhooked the battery and installed the new one. Late-model vehicles, however, rely on computers that operate everything from the stereo to the transmission. If power is lost to the computers, the settings are lost and reset to default. This means the vehicle may feel different when driven, and you may have to enter a security code to access the stereo.
