Solution

1. Preparation

Gather the necessary tools and materials: hairdryer or heat gun, lubricant (such as silicone spray or graphite powder), and a soft cloth.
Ensure the vehicle is parked in a warm area if possible.

2. Defrost the Locks

Heat Application:
- Use a hairdryer on a low setting or a heat gun, holding it several inches away from the lock to avoid damage.
- Apply heat to the lock cylinder and surrounding area for a few minutes until ice melts.
Check Functionality:
- After thawing, attempt to unlock the doors using the key fob and manual key.

3. Clean and Lubricate the Locks

Cleaning:
- Use the soft cloth to wipe away any ice residue and dirt from around the lock.
Lubrication:
- Apply a small amount of silicone spray or graphite powder into the keyhole and around the lock mechanism.
- Insert the key and turn it several times to distribute the lubricant evenly.

4. Final Checks

After applying lubricant, test the locks multiple times using both the key fob and manual key to ensure they operate smoothly.
If the locks remain unresponsive, further inspection of the lock mechanism may be necessary for internal issues.
