- De-icing spray or rubbing alcohol
- Silicone lubricant spray
- Towels

2. Remove Ice Build-Up

Use a hairdryer or heat gun on a low setting to gently warm the frozen area around the door lock.
- Ensure not to overheat any plastic components.
Apply de-icing spray or rubbing alcohol to the lock area to help melt any ice.
- Wipe away excess moisture with a towel.

3. Inspect and Lubricate Lock Mechanism

If the lock is still stiff after ice removal, remove any visible parts of the lock cover if applicable.
Spray silicone lubricant into the lock cylinder and on the moving parts of the lock mechanism.
- Work the lock back and forth to distribute the lubricant evenly.

4. Address Weather Stripping

Inspect the weather stripping around the door for damage or wear.
If damaged, replace with new weather stripping to prevent moisture ingress.
Ensure all seals are tight and properly fitted to reduce freezing in the future.
