Solution
1. Preparation
  • Ensure the vehicle is parked securely and the engine is turned off.
  • Disconnect the negative terminal of the battery to avoid any electrical shorts.

  • Replace the battery with a new CR2032 battery (ensure correct polarity).
  • Reassemble the key fob and test the trunk release function.
3. Check Trunk Release Switch
  • Remove the interior panel surrounding the trunk release switch using a trim removal tool.
  • Inspect the switch for any visible damage or loose connections.
  • Test the switch with a multimeter for continuity. If faulty, replace the switch.

  • Open the trunk manually if possible and inspect the latch mechanism for dirt or corrosion.
  • Clean the latch with electrical contact cleaner and lubricate it with a silicone-based lubricant.
  • Test the latch operation by pressing the trunk release button and observing its response.
5. Inspect Wiring and Fuses
  • Locate the fuse box and check the specific fuse related to the trunk release system; replace if blown.
