changed battery but cannot open car doors without the alarm going off, how do we reset the alram system so that I can drive the car.

Answer
almost all alarms have a by pass switch look under the drivers side of the dash you should see a toggle or a black push button turn the ing. to full on rt before it starts and push in or flip off the toggle switch.  this is what they call a bypass..Let me know how this works out .also let me know what kind of alarm sys you have.
