Got these along with a kit to connect my iPhone 6 to the '07 Audi S4 factory stereo/navigation package that now bypasses the external CD player mounted in the glovebox. Make sure you watch their You Tube video as the paper instructions enclosed were lacking - insertion of tool and extraction of head unit. Video is all you need and these work great - CD was out in minutes and the kit plugged in in less time. Highly recommended!

Only 2 keys in package
I thought I was buying enough keys to remove my stereo... 4 holes, 4 keys for $4.99.... wrong... there are only 2 keys in the package, so I had to do one side of the deck, then remove the keys by force and do the other side. So obviously 2 keys will work, but you'd probably be better off buying 2 packages or 4 keys.
