I drive a Peugeot 407SW year 2006
1. the blank does not fit into the lock - it is too thick
2. inside differs from the blank of the original, so you have to cut out / remove something, so that the board fits in.
The money for the blank, and the 25 for locksmiths were a wasted money ... because I foolishly let first grinding the blank and have tried him after that ...
