Keydiy KD-X4 Now Will Modify Original VAG MQB49 5C 5D Key ID !!!

Good News for everyone- the KEYDIY KD-X4 key programmre can modify the ID of original factory VAG MQB49 5C and 5D keys.
. In previous versions, the KD-X4 could only change the ID of the KD’s own 5C/5D keys. With latest update, the KD-X4 can also change the ID of original keys.

Fairly new update within the past few days.

Changing the original key ID will take 100 coins each time.


Example:

Done a VW ID.3 2021 MQB49 5D key. Changed factory key ID. Cost 100 coins to do. No SFD lock, 5D done today for ID.3 2021, changed factory key, cost 100 coins to do.

Used OEM board, second hand from ebay. Worked a treat, carefully split case, then glued together and reassembled. No one will even know. It does cost 100 coins to rewrite original board ID, but did the job.

To be fair KD FGB would be better option with the wireless remote generation. Without KD solderless adapter, you have to solder wires on the origina key.

NOTE:
Modify the ID of KD’s FGB remote does not require points.
CGDI K2 and YANHUA ACDP will also modify OEM 5C/5D key ID.

It will work without changing the ID, but it is recommended to use and ID of the exsiting factory position (when customer don’t have both keys) to avoid issues when it is performed programming with odis.

To use on position(ID) where sync exists on all modules. When a car modules is reprogrammed via ODIS online, the key will work; otherwise it will stop working. And other points.
