Not bad but not really good

I searched for my broken Peugeot 207 key replacement and actually is this folding key halfway useful. That is, you can remove the original key and insert the board in the spare keys, already he is in principle ready. But problems makes the key bit, so the silver end that you put in the ignition. When the original Bart is held by a small bolt, which can be easily removed with nail and hammer. I succeeded in replacing not, so the key is unusable.
