Well, yes. One in the passenger seat, one the driver.

It has NINE antennas (OK, four inside), I thought it could tell which key was where.

Not?

It can tell when you are standing just outside without the key inside!

Hmmm.... Have to go experiment some more. Hadn't considered it was confused in that way. I Just read through the documentation on it (those detailed, seeming training manuals posted elsewhere?) and it doesnt' really say whether it can tell which key is where.

Hmmm... interesting.
