Made the mistake to expand the printing mechanism ... was not necessary because a lot easier: cast out small splint from Bart and simply insert their own key bit. Take with a little skill 5 minutes. Needed the spare keys for a Peugeot 307cc Year. 2005. Did the way also removed pressure mechanism to get going again, just has only lasted longer ... even the battery tray must be removed for the 307cc inside the housing, which is namely on the board plan. Otherwise it does not fit. Otherwise the thing to work properly, unbeatable for the price. But rather for precision mechanics ... ;-))
