Solution

1. Preparation

Gather necessary tools: A soft cloth, a portable heater or heat gun (set to low), and de-icing spray.
Ensure the vehicle is parked in a safe area away from traffic.

2. De-ice the Locks

Using Heat:
- Hold the portable heater or heat gun a few inches away from the affected lock area.
- Move the heater in a circular motion to evenly distribute warmth, avoiding direct contact to prevent damage.
- Continue until the frost visibly melts.
Using De-icing Spray:
- Spray de-icing solution around the lock area.
- Allow it to penetrate the ice for a few minutes before attempting to operate the lock.

3. Test the Locks

After applying heat or de-icing spray, use the key fob or mobile app to attempt to unlock the vehicle.
If the locks engage, proceed to check all door locks to ensure functionality.

4. Lubrication

If the locks are operational, apply a silicone-based lubricant or lock lubricant to the lock mechanism to prevent future freezing.
Use a small amount on the keyhole and around the lock housing.
