My girlfriend was talking about buying an old grand wagoneer so i just bought a 76 iron pig to keep her occupied...(and to give me some fun too) 
Unfortunately its missing all the keys, PO lost them all. He said a locksmith was unable to make them on site. i’d like to make my own key for ignition and gas door.(and avoid the $75-175 replacements or locksmith fees) anyone have advice on how to hand file a key blank for a 76’ FJ55? Or anyone have any old ignition key/door key they want to sell? Ive read threads where guys hand filing a new key from a blank and also having luck using an ignition key from another FJ55 that is similar? But dont see any details on filing? Thanks!
