We changed out the battery and now the light is on and the raido wont come on and the car alarm with not go off. The clock is off - all dash lights come on, but no radio and the battery light wont go off. Do we have reset something?

Try putting your key in the drivers door lock and and, with all the doors and windows closed, lock and unlock the door 2-3 times. This usually re-sets the alarm, because the drivers door is the master lock for the system.
