Initialized, used Toyota 2-button smart key with a blank key. The model number listed on the circuit board is 271451-5300. It's an advantageous price because it has been initialized. Initialization is always required for re-registration. Keys that have not been initialized cannot be re-registered even if brought to a dealer. This product has been initialized, so it can be registered the same way as a new one. It is believed to be compatible with the late-model SAI, the early 40 series Prius α, and the 30 series Prius. You can use it if you open the cover of your current key and the model number on the circuit board matches. (The late-model SAI has 3 buttons, so the model number may be slightly different. I can check if you comment, as I have the actual vehicle.) *Please purchase at your own risk after checking if it is compatible with your vehicle, as it may not be compatible depending on the year. There are scratches from use, so please refrain from purchasing if you are sensitive to this. The operation has been confirmed to emit radio waves with a dedicated machine. The battery is removed, so please prepare it yourself. If you want to use it for a different vehicle, please inform the registration service provider of the following information beforehand and confirm whether it can be used before purchasing. A knowledgeable provider should understand. (If you are considering requesting registration at a dealer, they may not accept the bringing in of a used smart key, so please confirm in advance whether they will register it. It has been initialized, so it is in a state where it can be registered the same way as a new one.) type:4D+ DST80 Registration work is also possible within Oita city. If you wish, please consult in the comment section beforehand. Registration fee + 3000 yen will be charged. (I will adjust the listing price.) If you bought a used car and are worried about being stolen with only one key, you can also register only the necessary keys after deleting all registered keys. In that case, the key deletion fee + registration fee will be 5000 yen. (Keys that have been deregistered will no longer be usable.) Basically, it will be handled on either Saturday or Sunday. Your current key is required for registration. Please note that we cannot accept if you have lost all of them. Lexus 10 Aqua 18
