Service(?) Adviser(?)

I found my car's transponder key to be faulty. The vehicle remains functionally, however I am unable to remotely lock/unlocked the vehicle. I stopped over at VW Barons Bellville on my way to work to get advice and/or a quick fix. My query was directed to service adviser \DS."<br> <br> \""DS\"" inspected the key and informed me that the battery was faulty"
