Nerf the ID wire

[Solwra]

I think there should be a welder action at the start, like weakening the cover to the access panel. This could be a timed action like 2-3 seconds and can be repairable with a single sheet of metal, that also takes 2-3 seconds to replace. This would mean if you want to effectively hack without leaving much of a trace you will need to carry at least a welder and a metal sheet, plus waste additional 6 seconds sitting infront of a door performing an interruptible action that can give away what you're up to.

For high security doors, there should be an alarm and a requirement to cut additional wires in order to get access. For example, to get thru the armory door you now need to cut the alarm wire and 2 access wires, if you pulse the alarm wire it will blare out for 5-9 seconds. If you cut the access wire while the alarm wire is still intact it will blare out for 30 seconds.

EDIT: For the first idea, if the cover is missing it would be very obvious and inspecting the door it would let you know that the cover has been removed.
