How to open jammed trunk?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry to hear you're having trouble with your vehicle. If your SLK320's trunk won't open and the convertible top won't budge, there are a couple things you can try. First, ensure you can hear the lock mechanism releasing. If you can't, it may be a good idea to start by inspecting the fuse related to the trunk's lock mechanism. Next, try applying a little downward pressure on the trunk lid while releasing the latch. If these options don't work, it might be necessary to consult a trusted repair shop to open the trunk without causing unnecessary damage to the vehicle. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
