So after 5 days of near zero, I have had no issues.

I developed the NAD'S to wash it today.

Upper teens and doors are smooth and nice.

Well, it didn't work for me. It finally was warm enough to melt some snow, about 31 - 32 degrees. This evening, after watching the Steelers beat the ravens at the local club, we went out to the x. Drivers door handle was stuck, but not really bad. I did manage to open the door, but the door would not latch when I tried to close it. Also, the window was frozen and wouldn't go down. I guess I didn't have any problems over the last few days because it was so cold, there was no moisture. Since it did warm up a little, the moisture came back, and froze my door. It was worth a try. I ended up driving my x home while trying to hold the door from flying open. DO YOU HEAR THIS BMW? I am sure it won't make a difference, but I will be calling them tomorrow. Not the local dealer, but corporate.

31 degrees and still froze up? When you sprayed did you work
It in by repeatedley working the door handle?

Thanks for the help!! this will rescue me every morning

It got cold again, into the teens when this happened. It had been warmer during the day.

I took mine through the wash last night and this morning
@13 degrees it opened right up. It sucks to drive holding the
Door shut.

Keep a small sprayer in the car at least you can hit it if you need to.

I was thinking about doing this...but I wonder, what kind of small sprayer would work? I wish there was a pressurized type of de-icer or antifreeze with a straw extension (like a can of wd-40 has).

On a related note, I wonder if the RV antifreeze would work as well as glycol antifreeze. The RV antifreeze is non-toxic, I use it to fill up my return pipes of my pool every fall when I close it up. I bet it might work just as well...?

I don't think the pink stuff has the lubricants in it like the green has.

I keep it in a small plant sprayer.

Anyone ever tried this stuff? Seems like a nice small bottle that you can also keep in the car (along with jumper cables, air compressor, flashlights, etc....!) Keep in mind this is used as a fix to defrost and not as a prevention like the DIY coolant method. BMW does recommend to use lock cylinder grease to prevent the problem (far below). However both seem to be impossible to acquire in the states.

BTW, BMW also makes a silicone spray that might work as well as the coolant fix (though at probably 10 times the cost!).
