Hi there.

When the manual relearn doesn't work, that's usually an indication that the body control module (BCM) is no longer receiving the signal from the PASSLOCK sensor - all of which basically means the system needs to be diagnosed with the aid of a Tech-II or equivalent scan tool.

As an FYI, some customers report getting better and less expensive service from their local licensed locksmiths as compared to that from their GM dealers.
