OR do this
The ones the sequence that I posted doesn't work for should have
a 2-pin pigtail on the module. The most-common locations I know
of for the module are in the left-rear fender cavity in the trunk, or
the rear deck between the sheet metal the speakers mount in and
the deck's surface. Find the unused (i.e. no other wiring plugged
into it) pigtail, and using a paperclip or a short U-shaped piece of
wire, jumper the pigtail's 2 pins together. The module should click
when you jumper (short) them, and then each time you press lock
and unlock at the same time on a remote unit it should also click
to signify that remote's been accepted. Then do the next remote unit.
When it's accepted them all, remove the jumper from the pigtail.
