Replace or Recharge Battery

On the subject of battery disconnection does doing so change the ignition key in any way? Just the radio codes to contend with and the lapse in DME acquisition of driving data, is that correct?

Yes, disconnecting the battery does not harm the car. Mine is disconnected 5-6 mos. every year for the past 10 yrs. with no ill effects. I remove it from the car and sit it on my bench on a tender (garage is semi-heated but above freezing and stays 35-40 degrees all winter). Spring startup takes the DME 1 drive cycle to re-adapt.
