Where do you park your car? Inside a garage or somewhere else? I've noticed a lot of people that park their car in a garage and don't lock it tend to have more battery issues than those whom lock their car over night.

If the car isn't locked, and the key is within range, the car will never enter sleep mode, thus draining the battery fairly fast.

I leave my car for weeks at a time at an outdoor airport parking lot in -30C weather. Not once have I ever had my car not start or even had something like the comfort access not work.
