Can't remove anti-theft valve stem caps

Bought a C5Z a year ago, and need to fill air in the tires. Problem is I can't remove the aftermarket valve stem caps, they just spin when I try to remove them. There's no pin or anything like traditional anti-theft caps. I did some digging and it looks like the following:

However I don't have that tool that they come with. Any alternative method to get these things off? Or if anyone has a spare tool they could send I'd pay postage!

I would contact vendors that sell these for help.

Maybe some light pressure with a pair of pliers.

you just need to keep the valve stem from turning, likely whoever put them on last tightened them too much... hold the stem with one hand and loosen with the other

I would think any tire shop or garage would be able to help you.

They are doing what they are supposed to do

If you don't have the tool they came with, perhaps you could try to find the manufacturer to buy one, but in the mean time don't try to use pliers or pressure unless you want to destroy them

Right at the base of the cap there is a thin plastic lip (black) with 4 flat sides forming a square. This is the lip the removing tool grasps in order to install and remove the caps.

Get a 5/16 mini ignition wrench. Make sure its thickness is no more than 3/32, like the one in the 1st picture I'm attaching here.

Insert the mini wrench right at the base of the cap (see my 2nd picture) carefully going around until you correctly align it with the flat sides of the plastic lip and then unscrew it.

I hope my message is reaching you on time!
