Have had this on going problem and have gone thru 5/6 Deadbolt Lock kits .. The usual January Deep Freeze has come a month early, once the Temps hover around (-15'C +) the Front Door lock Tumblers are rendered useless with a Key.. We have decided to build an Insulated Front Vestibule / Mud Room come Spring.. We are a Southerly Exposure so the Hot & Cold hitting the Exterior Door doesn't help.. My Question as there had been a number of Reno's done by previous owners .. The location of a Heat Duct right in front of Main Front Door is a Contributing Factor (???) Thoughts & Opinions Appreciated, Cheers Thanks..
