How do I open the boot on Mitsubishi lancer sport back everything else is working?

To open the boot on a Mitsubishi Lancer Sportback, you can try the following methods: First, use the key fob to press the trunk release button, if available. If that doesn't work, check for a release lever located near the driver's seat or inside the glove compartment. Additionally, you can manually open the boot by inserting the key into the lock located on the boot itself, if your model has one. If none of these options work, there may be an issue with the trunk release mechanism that needs professional inspection.
