Yeah but hopefully he is is a Honda or Acura beign that he is on this site posting his problems. The Dodge and Chrysler vehicles are the biggest problems with multiplex systems and one wire door locks.The 2002 Buick Rendezvous,Ford Escape,and the 2002 Elantra and a few others are one wire but nothing in the Hona-Acura lineups were or are. They are all negative trigger systems except for the CRV(UK) version in 2001 which was a 5wire system, anyway it should be brought to a professional to do this work.
