yeah my bad, I was referring to computer spikes...
Security spikes help in unlocking doors and containers, just by having them.

As far as I know, security spikes are automatically used when hacking a computer for opening doors or disabling certain defences. When you have a higher skil in computers, you need less spikes for the same operation.
Same goes for repairing robots, you just need repair parts for them.
