1. Check the spare key: Try using the spare key if you have one.
2. Look for a manual keyhole: Some Mercedes-Benz models may have a manual keyhole for the boot, even if they primarily use keyless entry. Check around the trunk/boot area for a small, covered slot where you can insert a physical key.
3. Use the emergency release: Some vehicles have an emergency release cable or button inside the car that can be pulled to open the trunk/boot. Consult your vehicle's owner's manual to see if there is one and where it is located.
4. Try a locksmith: If you are unable to access the trunk/boot using any of the above methods, you may need to call a locksmith who specializes in automotive locks. A locksmith may have tools or techniques to open the trunk/boot without causing damage.
5. Contact Mercedes-Benz customer service: If you are still unable to access the trunk/boot after trying the above steps, you may need to contact Mercedes-Benz customer service for assistance. They may be able to provide guidance or arrange for a technician to help you.
