Solution

1. Preparation

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

2. Thawing the Locks

Use a hairdryer on a low setting to gently warm the lock area.
- Keep the hairdryer at least 6 inches away to avoid damaging the paint.
Alternatively, pour warm (not boiling) water over the lock to help melt the ice.
- Ensure to dry the area afterward to prevent refreezing.

3. Applying Lubricant

Obtain a silicone-based spray lubricant or de-icer.
Spray a small amount directly into the lock cylinder and around the keyhole.
Insert the key and gently turn it back and forth to distribute the lubricant.

4. Preventive Measures

Apply a thin layer of silicone grease around the lock cylinder to protect against moisture.
Consider using a lock de-icer spray regularly during winter months.
