Important! *Engines will not start on models equipped with an immobilizer (anti-theft device).* [Aftermarket Products] * For Hitachi H800 * For Kobelco K250 * For CAT * For Komatsu 787 (Master) (100/615/626/637/648/659/660/735) * For Kubota 459A (*Non-immobilizer models*) * For Sumitomo S450 Note: All 6 types are NOT compatible with models equipped with an immobilizer (anti-theft device). The engine will not start. All 6 types have been tested for operation using a key cylinder in hand. * As these are aftermarket products, the construction is rough. There may be uneven plating, discoloration, resin burrs, etc. These are products for those who only need to be able to turn the key cylinder. (Photos are reused when relisting) Again, these are not immobilizer keys with chips, so the engine will not start on models equipped with an immobilizer. * We do not handle immobilizer keys. * We cannot determine compatibility by model name or model number. The original key is the answer. Please judge based on the product photos and key number. We do not know about compatible models and will not respond to inquiries. * We cannot negotiate discounts, sell items individually, or change shipping methods. * We cannot change the shipping address after purchase (due to the anonymous transaction system). * Immediate purchase is OK. Please read our self-introduction regarding receipts, etc.
