Hi, I have an 2001 A4 and I'm trying to remove the standard stereo but only one pin engages the lock, the other two do nothing at all no matter how I push in, out, move left, right and the final pin is stuck in as this also did nothing and without looking I put this one in the wrong way and now it is jammed in the hole!!!

Could someone please advise how to remove this stereo considering only one key works and one is jammed in the hole.

Any advise is appreciated.
