2. Remove Ice from Locks

Using the heat gun or hair dryer, gently warm the door lock area to melt any ice.
- Safety Warning: Do not use excessive heat to avoid damaging the paint or plastic components.
Inspect the door seals and use the heat source if needed to clear any ice.

3. Lubricate Lock Mechanism

Apply silicone spray lubricant directly into the keyhole and around the lock mechanism.
- Move the locking mechanism manually (if accessible) to ensure the lubricant penetrates.
Wipe away any excess lubricant with a clean cloth.

4. Inspect and Repair Electrical Components

If the key fob is unresponsive, replace the battery and reprogram if necessary.
If electrical issues are detected, repair any damaged wiring or connectors found during inspection.
