Typically in the winter I go outside about 10 minutes before I plan on leaving for work and start my car, then go back in the house. I plan on doing the same for the MS3. Problem is, I haven't figured out how to leave the doors locked while it's warming up. I have the tech package so I have the advanced keyless entry. I've tried pushing the button on the door handle, pushing the lock button inside with the door open and then closing it, using the lock button on the remote, but nothing works. It's not like I live in a bad neighborhood, but I'd still like to lock my car while it's warming up. Anyone figure out how to do this?
