I don't know if this is of interest but I got fed up of the hassle in trying to unlock my aftermarket locking petrol cap.
I looked on the web for a replacement and could only find NOS ones at 190 Euros or 2nd hand ones at $100 which are prices I'm not willing to pay.
However, a bit of investigation found that VWH have ones, which come in VW Classic Parts packaging for £43.57, after Earlybay discount.
The part number is C 211 201 551/C and it's described as a "Clutch Plate"!
I've only had mine a short while but it feels to have far better build quality than the one it replaced.
Hope this is useful
