Hello friends. I am new roadster owner couple months. When i bought this beauty it was really bad condition. I got only 1 key which works only driver side door. Ignition start was with screw so i install keyless start button its works fine now. But i got problem with central key locking system. Key doesnt work with car. Car is europe model (uk) so i cant lock car car. If i try lock key with driver door is locking only driver door. Central console button works only UNLOCK button but not lock! So i bought universall central locking system like pic
