I have a 2010 Ford Taurus SEL that I can not get into.
This morning while leaving for work I was unable to open my driver door and thought it might be frozen shut. I tried to get into the passenger door but no luck. After trying all doors and not getting in I noticed the doors were all still locked.
I pressed the unlock button on my key fob, thinking the battery might have died overnight, but the headlights flashed as expected (I couldn't hear the usual sound of the locks unlocking though), and then when pressing the lock button the horn sounded and headlights flashed, again, as expected. I could pop the trunk and use the panic button as well.
I could put the physical key inside of the lock but when trying to turn it, it was as if I was using the wrong key (I wasn't...), and the lock wouldn't budge at all.
I took a cab to and from work today and when returning in the evening the situation hadn't changed. The temperature has been pretty low lately (around -15C), and today was an especially crisp -20C with -35C windchill (though I don't think the car would be any colder than -20C). There was also an ice storm recently that covered the car in a half-inch thick sheet of ice. Could it just be the case that the locks are frozen, or is there something deeper going on?
I have driven it daily for a good 2 years now and I'm sure it's been colder than this. I replaced the battery in the fall and my new battery has fewer cold cranking amps than my previous battery (don't know the figures, and can't find out as the hood pops from inside the car), so could this also be a factor?
Anyway, I'm getting really frustrated with not being able to get into my car and I don't want to spend $20+ just to commute again. If anyone could tell me what the problem could be I'd greatly appreciate it!
