This is the latest Vev2 model of an aftermarket key for a Lamborghini. The button design has been improved to Lamborghini specifications. This key contains a 315mhz remote control circuit board, the same as the original. It seems that by writing the PIN code with dedicated equipment, it can be used as a spare key, but we cannot guarantee that it will actually pair with the vehicle. There are tiny scratches on the chrome-plated part of the key head that do not appear in the photos, so please refrain from purchasing if you are looking for a perfect item.
