Cable lock for action packer?

I’m adding an air compressor and tow strap and I don’t want someone to be able to just lift out my action packer at night while camping. But I’m also lazy and don’t want to have to remove it everynight. It would be nice if I could somehow lock my AO soft cooler too. The problem is finding something that will sit through the action packer hole, although I guess I could just use a bicycle lock and lock it to the action packer with a regular lock?

Anyone had their fire extinguisher stolen?
