I always park mine in the garage even though it's a pain to get in there. We have a huge problem with auto theft here, particularly trucks. They were hacking GM vehicles especially through the onstar system. However, thieves are getting so advanced they are picking up the signal given off by any keyless entry type key. I'm considering getting a faraday bag to keep our keys in when we travel. It's crazy how easy they can take off with one of these and part one out.
