I am trying to replace/repair my passenger door actuator. In order to get to it I will need to disconnect the battery. Question I had in mind was, is disconnecting and reconnecting the battery is as simple as take the wires of and put them back on to the battery or is there anything else involved? After reconnecting would the radio and all electrical system would function back to normal or would I need something else........like a code......or take it to dealer for re-coding ........or anything else.

Any suggestions are welcome.
