General Locking wheel nut dust covers

[Robjlewis26]

Hopefully someone can help!
Noticed the locking wheel nuts on my Ducato motorhome have metal dust covers on them.
I have tried to remove them, but no joy.
The covers are round and only very small gap around the outside, so cannot get any sort of tool down to prize it off.
There was a black plastic tool in the glove box, but tried using that, still no good!
Please help! I have attached some photos.
TIA

Difficult to judge from photo, but will not a commercially available tool do the job? See examples from Ebay here.

Put the peg through the hol so its like a little sinl plunger. Pusu the plunger over the cover and wiggle firmly side to side, it should do the job. Needs to be wll on the cover though so it gets the rocking movement required
