How to Prevent Frozen Door Locks and Windows: Ultimate Winter Guide 🌟


Don’t Let Ice Ruin Your Day—Pro Tips to Stay Ahead of the Freeze!


1. Why Frozen Locks & Windows Are Dangerous ❄️

Every winter, 30% of roadside emergencies involve drivers locked out of their cars due to frozen doors or shattered windows (NHTSA). The risks:

  • Hypothermia: Spending minutes in sub-zero temps while struggling with locks.
  • Costly Repairs: Forcing frozen windows can damage motors ($200+).
  • Safety Hazards: Reduced visibility from icy windshields increases accident risks.

Key Stat: A frozen lock takes 5–15 minutes to thaw without tools—time you can’t afford in an emergency.
