I was reading on QW about someone that had their driver's side lock freeze where he couldn't get the key in the slot to unlock the door after a day of skiing (never mind the remote and not a C5), so he climbed in thru the trunk to the drivers seat. Another reader posted that since he had the cold weather package, all he had to do was to lift the door handle to start the "warming" process on the lock to thaw it?!?!?

Is this true or a load of malarkey?
