It will work for Chevy Trackers 99+ but I'm not sure if it will work for Geo's or Suzuki's
I guess if you have the RPO sticker in your glovebox it should work.

It should work for Geo's, all three of mine have had the glovebox RPO sticker.  Neither of my Suzukis has a GM RPO sticker.  Doubt their influence spread that far into the Suzuki world.

Seems right.
