Re: Door lock
When I said -5 I didn't mean that exact temperature I am just saying in the negative degrees one of the door latches always doesn't engage properly until warmed up maybe you got lucky but it is a known problem a lot of Cts owners have it and if you noticed like 7 new threads came up about the doors not working when the polar vertex happened ( or whatever is called )
We shouldn't waste any time arguing 99% it's the grease lets see if the person reports back and if it's not the grease we will help accordingly

It's more than likely a bad door latch. The arm that comes over the check arm to latch may have just worn out. You can use a flat blade screw driver to operate the latch manually so you can se exactly what isn't working.

Re: Door lock
After another 2 weeks of sub-freezing temperatures, I can report that after cleaning out the latches with WD-40 and then lubricating with a silicone spray, the latches are staying in operative condition even at single digit Fahrenheit degrees.
It is never a single reason for the latches freezing. A combination of lock/latch design, the grease can hold dirt and moisture differently, water drainage via glass slots, and the wind directions where you park outside will clog up the latch fittings and moving parts.
I believe that I have solved my own situation for now.
