Knowledge is learned from books. Experience is earned by actually doing something. You will only stick your whole finger in the latch once. The next time you will only use your finger tip to trip it. We call this a Guided Discovery Experience. Most novices learn quicker from these experiences.
victory! without putting my fingers into it it was just seized in the open position and wasn't an isuue till it was about -30 celcius then after work i discovered that the door hadn't closed just bounced back and there was some snow inside which then melted while i was working and froze again so now with the ice out and the latched cleaned and lubed i took her out for a spin and got the oil changed, tires rotated and balanced new air filter and fuel filter, i even found a floor cup holder at walmart(not as good as the old school ones)................. but what is?
I forgot it's cold up there. I had several cars in Illinois in winter that would do that. I had some kind of small spray bottle of clear smelly liquid to spray on things to melt the ice. "Lock thaw" sounds right. Then make sure you use a good thin lube like WD 40 or PB Blaster. Moving to Florida cured our icy door lock problem. But the limit for Canadians has already been met for this year.
