Removal of my keyfob from my account

Hello.
I’ve lost my fob. It has shutter and door access.

Can somone deactivate it and perhaps tell me how so I can write a how to.

Thanks
Fred

Okay…under the original system there is no user way to do this, or a clear admin route either

As as workaround I’ve disabled door and shutter access on your account until we get you a new fob
