XHORSE and KEYDIY now both support adding keys by reading the original MQB49 5C 5D key data. Some customers have asked us how to disassemble the VW Golf 8 style 5D smart key. We introduce three methods for reference. Hope it helps.
NOTE: For 5D system, only use original key to add a spare key.
Method 1

There is a small button on the side of the key. Press it to release the mechanical key.
