Hello The exchange with the original shell can not start up my car while it allows the operation of the locking and unlocking of my Peugeot 307 (2001). I solved the problem by keeping the rear of the hull that features the Peugeot lion and putting new front, Hull received. Thus everything foctionne correctly. It is therefore imperative to have the metal part of Peugeot logo in order to start up the vehicle.
My reasoning is false. See the answer below. After contact with the supplier, very competent, he had tranfer the transponder (small magnet located in the original hull and in a specific slot). Super service after sales. Congratulations Jongoshop for the speed of delivery (48h) and for giving me quickly bring the solution.
