Open the back seat of a 2002 Mercedes clk
I found these answers to the same question you had. 1. As long as your seats fold forward. You should be able to shine a light and either see your keys or pull the trunk safety latch. If your rear seats do not fold forward, you may have to unbolt them from the car. 2. I don't believe you can access the trunk from inside. Have the dealer make you a new key; bring your registration as proof of ownership.
