At one thime there was an adapter that used a 9 volt battery that you would plug into the cigar lighter. This would keep the memory of the computer going until you were able to repair the car or truck. Other wise you woulld have to tow the unit to a dealer and have it reprogram. It is called a memory adapter. The only thing you need to do is to make certain that the interior lights do not come on when the door is opened, and if you have a hood lamp that is disconnected. If no the little 9 volt battery will have a heart attack and short out, and you will lose the memory
