It's been a while since I had to do my first one, so I don't know. Now I use the online reporting facility, but I did have to use the drive-through for my first report after I got my new passport.
I would be inclined to try the drive-through. If more is needed they will tell him. Also, they tend to put the friendliest staff on the drive-through lane because they want it to be a success. Have always received friendly and prompt service from them using the drive-through. Worst case they will want him to go inside and fill out more paperwork.
