2013 Jetta All Keys Lost no Proximity. Can this be done without Vag OBD helper? Through OBD with VVDI2? Thank you in advance.
User working experience:
Just did one with NEC cluster. My first one. Key learn by 4th Immo – picked Jetta with nec xxxxx, none of the other types. Read Immo information. Saved bin file, made transponder out of superchip. Used an Xhorse remote and turned ignition on, then added a new OEM key.
You gotta read it then put cluster in service mode. It will give you a service mode dump. Then take that. Write to chip then you can put back in car or do all on bench take original file write back read immo data then make dealer key then add key. It gives you specific instructions once you click service mode on correct 4th immo operation.
VAG OBD Helper: succeed. I used vag helper. I did that, got immo data and learned key, it still asks to make dealer key then learn, no need to remove dash and make service mode. Car starts no problems and saved me taking dash out.
Xhorse VVDI2 recognizes that car has Johnson Controls dash but can’t retrieve data. I put Vag OBD Helper cable on and did online calculation.
I put the immo data from Vag Helper into VVDI2 but that’s as far as it goes.
Am I able to add a spare key ??
It worked finally:
step 1 : read car with OBD Helper Step 2: precode key with VVDI2 Step 3 : learn all keys to car.
I was able to add a key to a 12/2018 Golf 7 with JOHNSON CONTROLS as well as a 11/2018 Golf with a VDO NEC35XX. Both cars would not identify with the VVDI2 but I was able to make it happen with the vag helper cable.
