Review on 1K0905851B Ignition Compatible 2003 2013 Volkswagen by Brad Blake

All ignition parts require some effort and knowledge to install but are fairly easy to accomplish. However, if you need to use the key cylinder and keys, you need to reuse the RFID tablet from your old keys because they don't have it or the transmitter. This is easy and you just have to open the old key, remove the RFID tablet, open the new one and put it in the prepared hole.
