I recently picked up an 82 malibu wagon (second g body now, the other is a 79 s dr.). I got two keys from the p.o. One fits the ignition, the other fits the front door. The same door key fits the rear hatch, but won't unlock it. I had an 80 malibu wagon years ago, and I seem to remember it having three keys. (A third one for the rear hatch.) Can someone with a wagon tell me if this is the case, or do I need to tear into the hatch to figure out why the door key won't open it? (Actually I'm not sure I can do that with it closed...)
