My 90 525i came with a key that has a light in it to see better at night? Anyways I got these part numbers of the battery and light bulb. Battery(V625U) and the light is (*15V0155W). I called the BMW dealer here in Savannah and they told me I could only order the battery and the light was not replaceable?!?!? I told them the inner part of the key comes apart and the light is clearly replaceable but they want 52 dollars for a new key!!!! Does anyone know where I can order a light bulb and battery? Or did BMW create something that you cannot replace, which is not german of them, and have to throw away? PLEASE HELP!
