Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked in a warm area, if possible, to facilitate repairs.

2. Thaw the Lock

Alternatively, pour warm (not boiling) water over the lock area, ensuring not to get water inside the lock mechanism.

3. Clean and Lubricate the Lock

Tools Required:
- Lock lubricant (graphite or silicone spray recommended)
- Cloth or paper towel
Spray a small amount of lock lubricant into the keyhole.
Insert the key and turn it gently to distribute the lubricant inside the lock.
