My pal will get in literally any car with no damage at all.then he will take a reading from the ignition barrel ,cut key,plug in and code from special software. And away you go can lead to haveing to retumble locks as barrel are different to doors etc sometimes.oorrrrr if it is just a fob he can recode a fob and car to each other as long as the main dealer have released software to open market.if not main dealer only as said in earlier post
