Does anyone know how to remove an aftermarket stereo?

I installed this, but I've just slept too many times since then. I have the keys, but I can't feel anywhere at the bottom that they will go in?

I don't remember taking the whole dash apart, and if I remember the screws to do that are behind where the head unit is anyway?

Help.

 

Do you still have the install manual? What is the name brand? Might be able to find a .pdf on how to install it, and just reverse it. Does the keys you have fit into any of the slots behind the faceplate? Good luck!

I think most aftermarket radio keys go in the sides to release

 

The above responses are your answer. Get the manual out and use the 'keys' supplied as directed by the manual. MOST aftermarket units release by unlocking the tabs on the side, as illustrated below.
But the manufacturers vary a bit on exactly how the tab/key work together.
