Note: The engine will not start on models with an immobilizer (anti-theft device). ・We do not handle immobilizer keys. ・We cannot find a suitable key based on the model name or model number. The original key you have is the answer. Please compare the shape with the photos in the listing to make your judgment. We will not answer questions regarding compatibility as we do not know. [Items for Sale] ・Copy key for Yanmar, only 1 key (tested and works smoothly) This type of original key does not have a key number. It's a nameless key. The feature is that there are two consecutive recessed ridges on only one side. 301 is a provisional name (we use it for convenience, referencing part of the genuine part number). A431 V134 are the management numbers of the key blank manufacturer. ※ Although there is only one key pattern for Yanmar, it cannot be used for Kubota models because the key pattern is different. Not compatible with Kubota models. ・To reiterate, the item for sale is only one copy key. The photo of the key cylinder is only to show that we have tested it. The key cylinder will not be sent. It is not included in the sale. Please do not misunderstand.
