This time I just dried the rubbers and their counter surfaces and kept the doors open for a quarter or so when cleaning and drying all the door seals, sills and pillars. The automatic car wash is in an indoor car park so it is plus degrees there. With this new car the seal surfaces still have some oily feeling preventing freezing. In older cars I use some silicone wipe or my dad's method, wipe some glycol coolant to the seals. Locks are fine if you treat them with thin lock oil or gun oil before winter. I usually inject so much oil that it comes out and flushes some dirt out of the lock. Then clean the excess oil and you'll be fine for next winter or two.
If the lock freezes anyway, easiest way to get it working it is to heat the key with a lighter and stick it rapidly into the lock before it cools, this needs to be repeated couple of times. In past there used to be battery operated lock melting devices, that had an electrically heated thin stick, that could be sticked into any lock. But I haven't seen those in this millennium anymore.
