Solution

1. Preparation

Gather necessary tools:
- Hairdryer or heat gun
- Lock de-icer or isopropyl alcohol
- Silicone lubricant
Safety warning: Do not overheat the lock area to avoid damage to paint or plastics.

2. Apply Heat

Use the hairdryer or heat gun on the lowest setting.
Hold it about 6-12 inches away from the lock and move it in a circular motion to evenly distribute heat.
Continue this for approximately 1-2 minutes, checking frequently to see if the lock has thawed.

3. De-ice the Lock

If the lock is still frozen, spray a small amount of lock de-icer directly into the keyhole. If unavailable, pour a few drops of isopropyl alcohol into the lock.
Wait a couple of minutes for the de-icer to penetrate and thaw any ice inside the mechanism.

4. Lubricate the Lock

Once the lock is operational, apply a silicone-based lubricant into the keyhole to prevent future freezing.
Insert the key and turn it a few times to ensure the lubricant spreads throughout the mechanism.

5. Test the Lock

Use the key fob and physical key to test the lock several times to ensure it is functioning smoothly.
