03 Pathfinder 4x4. I am going to change out the vehicle battery. Will disconnection cause any problems with automatic locks or immobilizer or anything electronic? Also, want to change out fob battery. Any reprogramming needed after this is done.. Thanks

And radio presets will be reset too.
Remember to disconnect negative first when removing the old battery and reconnecting the positive first when installing the new one.

If you take off the positive first and slip with the wrench to ground - bad things will happen!
