3. Lubricate the Locks

Sub-steps:
- After the lock is thawed, apply a small amount of graphite or silicone-based lubricant into the lock cylinder.
- Insert the key and turn it gently to distribute the lubricant throughout the locking mechanism.
- Wipe away any excess lubricant from the surface to prevent dirt accumulation.

4. Test the Locks

Sub-steps:
- Test the key fob to ensure the electronic locking mechanisms are functioning properly.
- Attempt to lock and unlock the doors using both the key fob and the physical key.
