  • Sub-steps:
    1. Open the key fob using a flathead screwdriver.
    2. Remove the old battery and replace it with a new CR2032 battery, ensuring correct polarity.
    3. Reassemble the key fob and test the trunk release.
3. Check and Replace Trunk Release Fuse
  • Sub-steps:
    1. Locate the fuse box (usually found under the dashboard or in the engine compartment).
    2. Identify the trunk release fuse using the fuse diagram label.
    3. Remove the fuse using a fuse puller or pliers. Inspect for damage.
