Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a warm location if possible.
Wear gloves to protect hands from cold.

2. Remove Ice Buildup

Use a hairdryer on a low heat setting to gently warm the lock area.
Use a de-icing spray to melt ice around the locks, ensuring it penetrates the locks.

3. Lubricate Lock Mechanisms

Apply a graphite-based lock lubricant into the keyhole and around the locking mechanism.
- Important: Avoid using oil-based lubricants as they can attract dirt and grime.
Insert the key multiple times to distribute the lubricant evenly.

4. Seal and Protect

Use a silicone-based spray to coat the locks and prevent future moisture intrusion.
Ensure that the weather stripping around the doors is intact and replace if damaged to prevent water ingress.
