The trunk switch for a Mercedes-Benz is located at the bottom of the window lift switch on the driver's door. Pull the button upward for more than 3 seconds to automatically open the trunk. There is a trunk opening button on the Mercedes-Benz remote key, which is the first in a row of buttons. Press and hold this button to open the trunk.

I've been driving Mercedes for over a decade and often encounter locked trunk situations. The emergency opening method is actually quite simple: in most Mercedes models, there's a small pull cord or switch on the inner side of the trunk lid, usually located beneath or beside the panel - just reach in and pull to open. That time when my key battery died, this was how I solved it; just make sure it's not blocked by clutter. Another method is to fold down the rear seats and crawl into the trunk to find the pull ring, or use the mechanical key in the external lock cylinder. Regular trunk organization and checking the manual can prevent 90% of such troubles. If these don't work, don't force it to avoid damaging the car - contact a repair shop immediately.

As someone with extensive car repair experience, the emergency opening of a Mercedes trunk mainly relies on internal mechanisms. Many models are equipped with an emergency release pull ring or button on the trunk door panel—a gentle pull can open it. If not available, try using the spare mechanical key to turn the lock cylinder on the exterior of the tailgate. For some newer models, you may need to fold down the rear seats to access and operate from inside the cabin. Don’t forget to check for any foreign objects jamming the lock or wiring faults. If it’s an electronic system issue and temporary opening isn’t possible, seek professional assistance. Developing a habit of regular lock maintenance can minimize such occurrences. Overall, manual methods are safe and reliable.

In case of an emergency where the Mercedes trunk won't open, prioritize personal safety. For example, pull over to the roadside to operate it, avoiding risky areas with heavy traffic. Common emergency methods include: there's a pull cord inside the trunk, reach in and pull to open. If there's no response, avoid forcing it to prevent injury, and instead use the mechanical key or call for professional assistance. If someone is trapped inside the trunk, seek help immediately and refrain from attempting to dismantle car parts on your own. For prevention, learn the location of this function when purchasing the car and avoid covering it during daily use.
