Solution

1. Preparation

Gather tools: key, lubricant (graphite powder or silicone spray), hairdryer.
Ensure the vehicle is parked in a safe location.

2. Remove Ice

Heat Application:
- Use a hairdryer on a low setting to warm the lock area gradually.
- Keep the hairdryer at least 6 inches away from the lock to prevent damage.
- Focus on areas showing ice buildup, moving in a circular motion.
Water Melt:
- If ice is thick, carefully pour warm (not boiling) water over the lock to melt the ice.
- Wipe away any excess water and ice that may drip.

3. Lubrication

Choose Lubricant:
- Use graphite powder or silicone spray, as these are less likely to freeze compared to oil-based lubricants.
Application:
- Insert the key into the lock and apply a small amount of lubricant.
- Turn the key gently to distribute the lubricant within the lock mechanism.
Test Lock:
- Try turning the key several times to ensure it moves freely.
- If the lock is still resistant, repeat the heating and lubrication steps.
