Initialized used Toyota 2-button smart key. The model number listed on the circuit board is 271451-5300. It's an excellent price because it has been initialized. This product has been initialized, so it can be registered the same way as a new one. Initialization is always required for re-registration. 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 will check if you comment because I have the actual car.) *Please note that it may not be compatible depending on the year of the vehicle. Please check and confirm the compatible vehicle yourself before purchasing at your own risk. There are scratches due to use, so please refrain from purchasing if you are sensitive. The operation has been confirmed with a dedicated machine to check if radio waves are being emitted. The battery is removed, so please prepare it yourself. (If you are considering requesting a dealer, they may not accept the bringing in of a used smart key, so please check in advance if they will register it. It has been initialized, so it can be registered the same way as a new one.) type: 4D+ DST80 Registration work is also possible within Oita City.
