You know another place where people check your registration info is at car service places(known to have ex felons working there) so make sure you don't piss them off too bad at the lube shop or if you take your vehicle to get repaired. Don't ask me how i know.
Well that puts me back in the game of not programming my vehicles and getting the adapters to make it happen!
Just test it if it doesn't work they way you want you can erase it or your opener pretty easily, worst case it's still a little better than leaving an opener remote in the car. For new car you could probably test it on a test drive with some creativity. I suspect the more luxury brands may make a point of doing smarter things (there could even be some patent they have to license).
iirc, you park in the driveway and she parks in the garage. You could always do as nayr suggests in another thread and use an NFC tag and tasker or similar to trigger your future automation system from your phone instead of keeping the remote in the car (I actually do this too, but I'm considering some new phones without NFC). It's a great way to make sure you don't forget your phone.Yeah, but I'd have to buy the homelink adapter x 2... My wife and i will slum it with a normal garage door opener.
Mist German cars require key in. My sister last few bmw and her current 16 x5m require it.
I know there are wires within the mirror that only get power when the car is on for the compass and auto dimming mirror so modifying it is doable.
