Find a good locksmith, the big box stores cant make anything but a simple house key anymore. I have made spare keys for my boat, enclosed trailer, SxS and numerous other toys and the big box/ local hdwe store could not make any of them !! I have a good commercial locksmith not to far and he was able to make all ofvthe keys I needed. Keys are not cheap anymore, most are 10 bucks each in my area....a spare key ( fob type) for my Jeep was 140 bucks...ouch !!
