I have a 2008 Fx4 4x4 and this is the first time my drivers lock has done this. It's our first real cold snap (-30C) and my truck is outside at the cottage. I had my truck running for 30mins to let it warm up and went back out to shut it off but my keyless entry wouldn't unlock my drivers door. Even the unlock button from inside wouldn't do it nor my remote. I pulled it up manually and hit lock and it works fine. It just won't unlock. Any fixes before I take it in?

I'd check the fuse first. Don't know if you have access to a multi-meter, but I'd check that you're getting power to the lock solenoid before I took it in. It's pretty much going to be a bad switch or a bad solenoid. Shouldn't be that hard a fix, but if you have to do it outside in those temps I'd deal with it until summer. lol.

wouldn't a fuse effect my entire locking system and not just my drivers door? I have access to a meter and a heated garage when I head back home today

It probably would, but I don't know what all is on that circuit and it doesn't cost anything to check. I'd probably pull the switch panel off the door trim first and make sure your switch contacts are good and verify you're getting power to the switch. If that's good, then I'd check to see that you're getting power to your solenoid which means you'll have to pull your door trim panel off. That's not hard, but I don't know what kind of hand clearance you'll have to get to the solenoid connector. Once you've done that though and assuming you have power to that point, you're looking at a bad solenoid.

Glad it's back. Hopefully it stays that way.
