Stereo & Electronics - bcm schematics

does anyone have the schematics for the bcm. I would like to try to extend the range of our keyless entry and know the antenna is internal, but a schematic would be a great help.

thanks.

I doubt you'll find one. The BCM is considered a non-serviceable part even for the GM/Delco repair centers that fix radios. There are no internal BCM schematics in the GM service manuals.

But if you do find one... I'm sure there are other members here who would be interested in them.

appreciate it. has anyone taken one apart? pictures?

has anyone had luck extending the range at all?
