Disconnecting the battery on some computerized vehicles can also cause issues. You may lose any pre-set features such as radio stations and clock settings. Also, some radios have a anti-theft feature that requires a code to unlock them after battery power is lost. Make sure you have the code if this is the case, check your owner’s manual.
