How do you remove a porsche stereo?
 

I have recently bought an Alpine stereo system for my Boxster. I was given some keys by the retailer but they didn't fit so i returned them, they didn't have the correct ones for my stereo as the holes for the keys are horizontal not vertical.

I then went to Halfords and they tried about 20 pairs of keys to remove the unit, still no joy! Has anyone got any advice on this? I am desperate to fit the stereo but cant get the original out!!!

HELP.

It is just a matter of sticking the keys in, then pushing outwards with the part that is still extended, and pulling the radio out. You can't just stick the keys in and try to pull straight towards you without pushing the keys sideways to release the catches. Should take all of about 4 seconds.
