EvDraper

This car was purchased new in 2005 by my daughter. I got is from her two years ago. The odometer now reads 228,000. Last year I replaced the front oxygen sensors and today I replaced the battery. Since the battery was replaced, the electronic ignition key does not work for opening and closing the doors and trunk. I realize that the key may need a battery, but there were no issues before the car's battery failed. If the ignition key needs to be reprogramed, how can I do it?
