So I have a Pi4 and Pi Zeros and I am using a Zymkey 4i with both and I am looking for a way to remove/clear keys to basically “zeroize” the device on demand.

I know I can bind with production and then turn on Perimeter detection and that will zeroize on a trip but what if I want to do it on demand? I saw there is a remove\_key() but that doesn’t seem to be implemented, is there some other interface I can use to blow away keys in python or bash?

@joelcomp1 - The Zymkey 4i does not support removing/clearing the keys on demand via the APIs.
