Here are step-by-step instructions:
Locate the lock cylinder: On a 1997 Mercedes S320, the lock cylinder for the trunk lid is located at the center of the decklid, below the Mercedes-Benz emblem.
Look for the rubber cover: There is a rubber cover that conceals the lock cylinder. Gently pry open this cover using your fingers or a flat-head screwdriver.
Insert the key: Once the rubber cover is removed, you'll see the keyhole. Insert the metal key that came with your vehicle into the lock cylinder.
Turn the key: Once the key is inserted, turn it clockwise while applying gentle pressure to the trunk lid. You may need to wiggle the key slightly while turning it.
Apply gentle pressure: As you turn the key, gently push down on the trunk lid as if you're trying to open it.
Unlock the trunk: If the lock mechanism is functional and the key is still operational, the trunk should unlock, and you'll be able to lift the lid open.
Note:
* If the trunk won't unlock even after following these steps, there may be an issue with the lock mechanism or the key itself. In such cases, it's advisable to consult a professional automotive locksmith or visit a Mercedes-Benz dealership for assistance.**
