I am trying to locate some Transmitter Micro Chips for the key fob I just purchased. P/N 88 88 1 600 211 - 3 Chip Set P/N 88 88 1 600 217 - 4 Chip Set I believe both part numbers were superceded by P/N 82111467000. For some reason the Key Fobs are available but not the Microchips to make them work. If anyone has a lead on locating these chips, let me know! Thanks!
