1. Locate the emergency trunk release: It is usually located in the glove compartment or under the rear seat.
2. Pull the emergency trunk release: This will release the latch and allow you to open the trunk.
3. If the emergency trunk release doesn't work, you may need to try using a slim jim or other tool to manually release the latch. Be careful not to damage the lock or surrounding trim.
4. Once the trunk is open, you can turn the key to the vertical position and remove it.
5. Lubricate the lock with a silicone-based lubricant to prevent it from sticking again.
