If thats what you did, then you were probably locked out by the pats system.

A frozen starter makes a lot more sense than a battery problem in my opinion. Conditions were brutal (-42C) at the time of the problem. I did trying tapping on it however to no avail.
Both keys used were OEM programmed keys so it doesn't sound like it could be PATS.

I am having trouble believing the battery theory for a few reasons, a couple of which I neglected to include in my original post.
First, the truck had only been sitting a couple of hours. I just finished driving it home from work (truck was running for more than an hour). It had been sitting all day in the cold weather prior to that and had NO issues starting at that time. The truck has never had problems starting previously and has never at any time turned over "slower" than normal.
Secondly, when the truck wouldn't start, there was still plenty of power for all of the accessories including the interior lights, headlights, radio, and heater fan running on high. I find it hard to believe that the battery could be so dead that it couldn't even turn over the starter yet power everything else flawlessly.
Lastly, as mentioned, a boost was completely ineffective.
I just heard back from the dealership and they are trying to tell me a frozen battery was the culprit. I am NOT buying it. They brought it in, warmed it up, charged it, and tested it and said everything checked out fine. Oh..........but........before I go, I owe them $87 for the "diagnosis" because a frozen battery is not covered under the Ford Warranty, it is owner negligence.
I am furious, this is not acceptable. The service manager wasn't in for me to speak to but I refused to pay and said I would talk to him tomorrow.
I am convinced this was not a battery problem. Furthermore, I would bet that whatever was causing the problem was "healed" when the truck was brought inside to warm up at the dealership.
I would sure love to hear some other theories on what this could be. Is there any way that this could be a PATS problem? A couple of different sets of keys and keyless remotes were used shortly prior to the problem, could they somehow have triggered something? Or could it have possibly been the starter relay, solenoid, or starter? Any other stupid little thing it could be? Thoughts?
Once again, this is a 2007 with less than 25,000 kms (15,000 miles) of almost all summer highway miles. It is still pretty much a brand new truck.

My truck would not start the other day when it was cold and I too thought it was the battery. Turns out it was the starter relay in the fuse box. It some how got condensation in it (moisture in air from 3rd brake lamp leak?) and rusted to where it would not start. I figured it out by swapping the relay with the high beam relay. Hope this helps someone.

Again, not acceptable. My next step will be a chat with Ford Canada.

Dude, it was -42 and you can't 'fathom' a frozen battery?

Talk about -42C brings back memories of the days I lived in Canada. I feel for you guys, I really do. Starting cold engines at -42C without snapping any of the moving parts is what I call lucky. Expecting a battery to perform in that demanding, harsh condition shouldn't cause a surprise if it fails to start the engine.

If I had left the truck sitting in those conditions for a week, it would be a different story.
Not to mention that if anything froze the battery it would be from sitting outside the dealership for 3 days waiting for them to get to it.

Hi guys I am having the same problem with my 07 King Ranch. I have already replaced the battery with a Optima and have had it tested at Oreilly and it came back good.
What was the fix for yalls trucks?

I still don't know what caused the problem I had. Once it warmed up, everything was fine and the issue has not occurred again. I suspect that this winter when it gets to -40C, the problem will resurface.

I went through three batteries on my 05 Screw in three years. I now have an 08 Screw King Ranch I bought in Feb. I went out yesterday after it sat for two days and it was dead. It is at Ford right now and of course they can't find anything wrong with it. . . 
I am convinced these batteries are POS, because the last one I changed out on my 05 screw was out of warranty, and I bought an aftermarket which lasted longer then the motorcraft batteries. It was still ticking when I traded in my lease.

BigFly and cndcowboy do you know how to read the battery voltage with a meter? If so please do so and post the voltage along with how long it has been since the truck was driven. I am having the same problems with my 07 King Ranch. See this thread: http://https://www.f150online.com/fo...ne-week-3.html

12.6 when I park, the next morning it was down to 11.4, that was with nothing plugged in. An update to my 08 KR issues, they did a charging system check at Ford and couldn't find a problem. The battery was working fine for them, but after I told them about my voltage numbers they replaced the battery anyway. The starter turns way faster now. No problems since the replacement.

What does voltage drop to now overnight with the new battery?

I'll have to wait until I am home. I am working about 1000 miles from home right now, so I have my truck but not my voltmeter. From what I recall with the 2005 was no lower than 12.4 after a couple of days. It will be about 3 weeks until I can check for you.
