Inspect the lock for corrosion. If corrosion is found, clean it using a wire brush.
Use lubricant spray (preferably silicone-based) on the lock mechanism to prevent freezing.

4. Replace Weather Stripping (if necessary)

If the door seals are damaged, remove the old weather stripping.
Clean the area where the new weather stripping will be applied.
Install new weather stripping, ensuring a tight seal to keep moisture out.
