I thought I should share my experience of adding an extra remote locking fob to the Citigo using VagCom, as the procedure that eventually worked seems pretty much undocumented.

 

Background:

    I used genuine VagCom software and cable - I've no idea if clones will work.

    The control module to use is 09 - Cent Elect (the locking functions seem to have been merged here in later models)

    Note this does not associate the immobiliser. If you want to upgrade from a dumb (valet) key, then it's best to extract the transponder from that and replace the one in the new keyfob with the old transponder.

 

Steps:

    1) Turn on ignition with a working key.

    2) Connect VagCom and select 09-Cent Elect

 

    3) IMPORTANT: Switch off ignition and remove existing key

 

    4) Select "Learned Value Clearing" from drop down menu. Then "Save" - this clears all existing fobs.

    5) Select "Remote Control Adaptation (Key Count)" from drop down menu - and then "Save" (Do not attempt to set the value to anything other than 1)

    6) Push and hold the open button on the key fob until you hear a tone from the dash.

 

To add another (or re-add if you cleared existing fobs)

    7) Re-read the "Remote Control Adaptation (Key Count)" (or just select it again from the dropdown) - then "Save"

    8) Push and hold the open button on the next keyfob until you hear a tone from the dash.

 

All done. This took a fair bit of experimentation so I hope it can help someone.

Thanks for sharing, but I am not clear what you are achieving. Sorry.

 

Does this just add an extra key fob for locking and unlocking only unless the tiny (and fragile) transponder is swapped over?

I'm afraid so. It's a way of upgrading the second key to one with a locking fob a little cheaper than having it done at the garage (assuming you have access to a VagCom). The transponder swap can be fiddly it's true - I believe there are other ways to associate a new fob to the immobiliser but it would require specialised hardware/software.

Thanks for clarifying.

I already have two keys that have immobilisers in, but could do with a 'dumb' key for when I'm out and about just to be able to lock the car.
