Bolt cutters would make quick work of those cables; but if you don’t already have some, you might see if you can get a couple of flat head screw drivers into the top of the notch where your fingers are in the picture. I’m guessing that’s part of where the plastic cage comes apart when it’s unlocked, so it could be a good leverage point if you wanted to try just forcing it open.

Uh. Any help?
Overkill. Any multi-tool or pocket-sized wire cutters will make fast work of this.
