y5: didn't you get a key with those locks (as pictured)? It came with my locks when I ordered from the dealer. I don't believe there's a standard key for all BMW locks (at least a few variations).

As for the 214s and swapping. This is exactly why I went with all-seasons, but I realize people have worse snow than NY. When I still had my 19" 212s on, the 214s from wheelsandcaps (reps usually heavier?) were about 50lbs each in 4 boxes. Somewhat heavy but manageable. They all fit in the trunk of the X with the rear seats folded, but it was a royal PITA. Now imagine there's rubber on each of them. After I got my install, he packed the 4 212s w/tires back into the rear and it barely fit [without boxes]. Getting them out by myself at home was a job and a half. That's a LOT of weight to grab from a height, not to mention the awkward angle. You can easily hurt yourself if not careful.

Anyway, I had no intentions of keeping them (sold them) but if I did I would've had to leave it out in the backyard (actually I did when prepping them for sale). They're way too bulky and much of an eyesore anywhere other than there or the garage. I thought I heard some shops who swap tires for you will store them for you, but there's gotta be a catch - I don't see much room at the shops I go to. If you can survive with them (and I have through a few snowstorms in 2 years), save yourself time, effort, and money - go with all-seasons and leave the 214s on year-round.
