When I read the many reviews, I was hesitant at first. But somehow I had to find out on the radio. I bought 2008, the release key for the original Radio 6000 CD in my Ford Fusion Year. The keys are quite thin. Must indeed fit into the narrow slots of the radio. But they are still stable, although the are so thin. The key raced with an audible and perceptible "click". Then the radio read easily pull out of the mounting bay. 5 stars for the release key, because it the original radio was so light and easy to expand. And for such a reasonable price, I can only recommend to all.
