So I get back to my car in the airport parking lot on January 1st to find a message about my 12V battery being low and to call service. Ok I was expecting that as it's my original battery and lasted two years which I understand is well above average. Drive home and call service the next day, get an appointment in just over a week. So far so good. Fast forward a bit and I get a call from service to the effect they just ran out of 12V batteries so we reschedule to today. Well they called again last night to advise they still don't have a 12V and they are on backorder from California. They (Montreal) still don't know when to expect the batteries and they can't borrow one from Toronto either because they're all out too. Now I'm starting to get nervous as it's going on three weeks with a low 12V in the dead of winter and I have to leave my car unplugged at work for several days at a time. Am I one cold snap away from a dead car? And suppose I do get back to a dead car, is there any way to unlock the doors? I might want to pry off the nosecone to access the battery terminals but if my cables are in the trunk, they wont be of much use. Anyone done this before?
