It is probably his RAP module or something that is clicking. Moving to the General Explorations section.

what the hell is a RAP modual and what does it do ?

can he still drive it ?

RAP module is the box for that controls the alarm/keyless entry system. Does it seem like its coming from the area where the jack is located?

edit: Just realized its a 2002. Not sure what it is.. I don't have a 3rd generation vehicle sorry.
