  1. don’t know how to fix this one, but for the future one can purchase a device that plugs into the cigarette (power supply) lighter and the other end has a standard 9 volt battery. You can change the battery and it keeps the radio codes, digital devices on the dash and the key codes.

    1. Don – Thanks for adding to the discussion. Yes, there are several of these types of devices. We offer our ESA30 OBDII cable that can be used with a jump starter to preserve vehicle presets as well as our 1924 Memory Saver unit to perform the same task as a dedicated unit. Thanks again, Jim from Clore Automotive
