Cold Weather Door Latch Issue

Does anyone know of any tips to get the door to latch during the winter months. I'm in an area of WY that is always below freezing and frequently single digits or colder. It seems that when the outside temp hits the teens, my door latches just don't want to work. It seems like they freeze up and won't latch. It makes for a chilly ride. Any suggestions?

Have you tried to put some dry graphite on them? Not just the lock cylinders, but the latch mechanism itself.

One thing that adds to this problem is the door seals get stiff in the cold, don't know what can be done about that though.

RR Classics have heated door locks. Maybe you could adapt the lock barrel heater from one of those.

I your door seals are old they'll be more stiff than new ones. For the lock the only option in very cold weather is something like a moly grease rated for that temperature range and cleaning out any waxing before application and then changing it in the summer since it'll probably run out when warm. That being the 'right' way, if you lube with something like light machine oil (3in1 is a brand) it'll probably stay more fluid than a lot of the spray and evapourate type lubricants. (and never ever lubricate with WD40 or any other penetrant, they're solvents not lubricants).

Hope that helps, the more fun one is when the doors freeze onto the door seals themselves, I'm going to put on one of the aftermarket seals at some point and experiment with different treatments to stop it... I'm guessing that regular application of something like armorall might work...

I have run into this problem. I have found that squirting with a little hoppes Dri-lube works fine for me. I have had the door seals freeze with water on them before. that sucks.
