Need a replacement Alloy Wheel Locking Key

[Joss Apps]

Hello, simple question. Where to get a replacement alloy locking key? I'm sure it was where I left it but can't find it even after a full empty of our Cali. Image of alloy bolt attached. Bought 10 years ago and can't remember if it's a VW supplied set or a third party one. I've seen a couple of adverts on Ebay offering to match a photo, anyone used them. Any help much appreciated?
