Solution

1. Preparation

Gather the necessary tools and materials.
Ensure you are working in a well-lit environment to see clearly.

2. Remove Ice or Frost

Tools Required: Warm water in a spray bottle or a hairdryer.
Sub-steps:
1. Use a spray bottle filled with warm (not boiling) water to carefully spray the frozen lock area.
2. Alternatively, use a hairdryer on a low setting to gently warm the lock, ensuring not to overheat any plastic components.
Safety Warning: Avoid using boiling water as it may cause thermal shock to the metal components.

3. Lubricate the Lock Mechanism

Tools Required: Graphite lubricant or silicone spray.
Sub-steps:
1. Once the lock is thawed, apply a small amount of graphite lubricant or silicone spray into the lock cylinder.
2. Insert the key into the lock and turn it multiple times to distribute the lubricant evenly.
3. Clean any excess lubricant from the exterior surface of the lock.

4. Inspect and Repair Weatherstripping

Tools Required: Utility knife or scissors (if replacement is needed).
Sub-steps:
1. Inspect the weatherstripping around the door for any tears or gaps.
2. If damaged, cut away the old weatherstripping using a utility knife.
3. Replace with new weatherstripping, ensuring a tight seal to prevent moisture entry.
