When a Vault is destroyed, a "Vault protection pylon" appears and starts to spawn enemies. It decays and triggers an explosion if it reaches zero.

According to the research option "Interplanetary Construction 1" I should capture it. The Factoriopedia entry for the pylon says it "can be hacked with Vault security key" to create "Interplanetary warp pylon".

But how do I do that? In this mod "hacking" is normally done by shooting a Vault access key into a Vault access console, and the Vault security key has the Vault protection pylon as a possible target filter. I tried shooting the protection pylon with a sec key in a submachine gun, but that didn't do anything. I tried surrounding it with sec key Gun turrets that have the protection pylon as a priority target, but to no avail: https://fb.hash.works/9yc7KYlE/

What am I missing?
