I just got an 04 Blazer with almost all of the goodies.... except it
was a rental unit, with no keyless entry. No RCDLR (receiver)
installed, just the wiring harness plug for it. If I get a receiver
and key fobs (and program the receiver for the key fobs), do I have to
use a tech 2 scan tool to tell the BCM that it has keyless entry??? I
am assuming that I would need to since the class 2 modules send a SOH
every 2 seconds, the BCM probably needs to be told the vehicle is so
equipped. Or will it just learn when it hears the RCDLR on the data
buss and unlock the doors when the command is on the buss??? Ya gotta
love all of the wiz bang stuff on the newer vehicles!!! Thanks for
any insight, the sevice manual is somewhat vague.

Is anyone familiar enough with the factory keyless entry hardware to
be able to tell me where the receiving antenna is? My '99 4-door has
terrible keyfob reception range. Even with new batteries in the
keyfobs I have to be within 8 feet of the car.. I would really like
to reorient or possibly even relocate the antenna to improve reception

The antenna is "self contained" within the RCDLR which on the '03 and
'04 is located (or in my case would be located) on the top side of the
insulating panel directly above the driver's left foot, toword the
front of the car (behind) the data link connector.
