I have the Driver 1 remote in my pocket and my wife has the Driver 2 in her purse. The only time it gets confused--and it happens every time-- is this: I remotely open the rear with my remote, unlock the front door and start the car. My wife is loading in the back. It always defaults to Driver 2.

I will have to try it when she is not there and see what happens.

 

Is there a question here? Report back once you've tried it without her key. Also try it with driver 2 in your pocket and driver 1 in her purse.

 

Ours does something like that as well. If my wife and I walk into the garage together and I (Driver 1) open the drivers side door as she's walking around to the passenger side it'll usually (but not always) set to her (Driver 2). I have to close the door and open it again for it to set to me. We haven't figured out why it does that. It's a little aggravating but kinda humorous too. She says it's because it likes her more. Then again, it might because the RDX is indeed more feminine as one of the forum denziens was claiming a while back (actually, he said it's 'vaginal').
